DETAILED DESCRIPTION FIG. 1 is a perspective view of a gondola shelving assembly 100 made in accordance with the present disclosure. The gondola shelving assembly 100 includes a plurality of gondola shelving units 102 and an end cap shelving unit 104. All of the gondola shelving units 102 and the end cap shelving unit 104 include shelves for storing and displaying physical goods. As illustrated in FIG. 1, the gondola shelving assembly 100 may include various types of shelves for storing and displaying products. As further illustrated in FIG. 1, the gondola shelving assembly 100 includes two gondola shelving units 102, but may include more or fewer gondola shelving units 102. FIGS. 2-24 illustrate the steps of an example method of assembling the gondola shelving assembly 100, and provide detail as to various components of the gondola shelving assembly 100. FIG. 2 is a perspective view of a partially assembled gondola shelving unit 200. The partially assembled gondola shelving unit 200 includes a first upright 202 and second upright 204. Illustrated in FIG. 2 is a possible first step of assembling the gondola shelving unit 102 of FIG. 1. FIG. 2 illustrates positioning the first and second uprights 202, 204 separate from one another and coupling the first and second uprights 202, 204 with front sway braces 206. Each of the first and second uprights 202, 204 are rigid frames for the gondola shelving unit 102 of FIG. 1. The first and second uprights 202, 204 are identical, but in some examples, the first and second uprights 202, 204 could include structural differences. As illustrated in FIG. 2, the first and second uprights 202, 204 having a top end 212 and a bottom end 214 opposite the top end 212. In the present example, the bottom end 214 includes a plurality of footpads 216. In various examples, the footpads 216 are height-adjustable to stabilize and level the gondola shelving unit 102. The first and second uprights 202, 204 also have a central channel 222 and two front tubes 224 disposed opposite each other. In some examples, the first and second uprights 202, 204 include a central channel 222 and one front tube 224. The central channel 222 is parallel with the front tubes 224, but in other examples, the central channel 222 and the front tubes 224 could be angled relative to each other. As illustrated in FIG. 2, the central channel 222 is coupled to the two front tubes 224 via horizontal struts 226. In the present example, the uprights 202, 204 are made of a rigid material capable of supporting the weight of products disposed on the shelves of the gondola shelving unit 102 and above the gondola shelving unit 102. For example, the uprights 202, 204 could be made of metal (e.g., aluminum, titanium, steel), polymers (e.g., plastic), ceramics, natural materials (e.g., wood), or any suitable combination of materials. In the present example, the central channel 222 and the front tubes 224 are secured together either because they are manufactured as a monolithic object with the horizontal struts 226 or because the horizontal struts 226 weld the central channel 222 and the two front tubes 224 to form a unitary piece. The partially assembled gondola shelving unit 200 includes the front sway brace 206 removably coupled to the front tube 224 of the first and second uprights 202, 204 and adjacent the top end 212. The front sway brace 206 includes a front surface 232 and two coupling shoulders 234 to engage the front tubes 224. In the present example, the shoulders 234 include angled teeth 236 to engage angled slots 238 disposed on the front tube 224 adjacent the top end 212. In some examples, the teeth 236 are L-teeth to engage the slots 238, but the teeth 236 could comprise any protrusion capable of engaging an aperture in the front tube 224 and securing the front sway brace 206. In the present example, securing the front sway brace 206 to the first and second uprights 202, 204 provides sufficient stability for the partially assembled gondola shelving unit 200. The front tube 224 includes angled slots 238 that engage and secure the teeth 236 (shown in greater detail in FIG. 3). When the teeth 236 securely engage the angled slots 238, the teeth 236 engage the slots and pull the shoulder 234 against the front tube 224. When the front sway brace 206 is secured to both the first and second uprights 202, 204, the partially assembled gondola shelving unit 200 is rigid and stable. In various examples, shelves could be coupled to the partially assembled gondola shelving unit 200 and product displayed on the shelves without further structural elements. FIG. 3 illustrates partially assembled gondola shelving unit 300 including the first and second uprights 202, 204 being coupled with cross braces 302, 304. Illustrated in FIG. 3 is a possible second step of assembling the gondola shelving unit 102 of FIG. 1. The second step can include coupling the first and second uprights 202, 204 with cross braces 302, 304. The cross brace 302 is removably coupled to the central channel 222 adjacent a bottom end 214 of the uprights 202, 204. Similarly, the cross brace 304 is removably coupled to the central channel 222 at a position centrally disposed between the top end 212 and the bottom end 214. In the present example, the cross braces 302, 304 engage a bracket 402 (illustrated in FIG. 4) disposed on the central channel 222. The cross braces 302, 304 may provide additional structural support to the partially assembled gondola shelving unit 300 and prevent the assembled gondola shelving unit 102 from buckling under weight or falling out of square. However, in the present example, the front sway brace 206 provides all necessary rigidity to keep the gondola shelving unit 300, 102 stable and secure. FIG. 4 is a perspective view the bracket 402 for coupling the cross brace 304 of FIG. 3 to one of the first and second uprights 202, 204. As shown in FIG. 4, the cross brace 304 includes a tab 404 to engage the bracket 402. The bracket 402 includes an aperture 412 configured to receive the tab 404 of the cross brace 304. For example, as shown in FIG. 4, the tab 404 is a thin sheet, but in other examples, could be differently configured. In the present example, the bracket 402 is secured to the central channel 222 and, in various examples, may be integrally formed with the central channel 222, welded to the central channel 222, glued to the central channel 222, or secured in any other similar manner. Similarly, the tab 404 can be integrally formed with the cross brace 304 and bent into position or can be secured to the cross brace 304 in any appropriate manner. In various examples, the cross brace 303 is coupled to the first and second uprights 202, 204 in an identical or substantially similar manner. As discussed in greater detail in connection with FIGS. 14 and 16, The central channel 222 includes a plurality of slots 432, facing the front tube 224. Each of the slots 432 are adapted to receive an L-tooth commonly used in shelving systems. FIG. 5 illustrates a perspective view of a partially assembled gondola shelving unit 500 including disposing panels 502a, 502b, 502c, 502d between the first and second uprights 202, 204. As illustrated in FIG. 5, the partially assembled gondola shelving unit 500 includes four panels 502a, 502b, 502c, 502d, but in various other examples, could include more or fewer panels. The panels 502a, 502b, 502c, 502d are disposed in inwardly directed channels 512 (illustrated in greater detail in FIGS. 4 and 6). As illustrated in FIGS. 4, 5, and 6, the inwardly directed channels 512 could be U-channels, C-channels, or any similar channel capable of removably receiving the panels 502a, 502b, 502c, 502d. In some examples, the inwardly directed channels 512 are sized to hold the panel in place with friction. As shown in FIG. 5, the panel 502c is slid into the channel 512 and, in a similar manner, panels 502a, 502b, and 502d are slid into corresponding channels 512. In other examples, the panels 502a, 502b, 502c, and 502d could be removably coupled to the partially assembled gondola shelving unit 500 in other manners including clips, magnets, fasteners, etc. In various examples, the channels 512 are made of any suitable material, including metal and plastic. Illustrated in FIG. 5 is a possible third step of assembling the gondola shelving unit 102 of FIG. 1. The third step can include inserting panels 502a, 502b, 502c, 502d into corresponding inwardly directed channels 512. In the present example, the inwardly directed channels 512 are disposed perpendicular to the slots 432 and adjacent the cross braces 302, 304 when the cross braces are coupled to the central channel 222. As a result, the panels 502a, 502b, 502c, 502d cover up the installed cross braces 302, 304. In some examples, the panels 502a, 502b, 502c, 502d assist in inhibiting the gondola shelving unit 102 from leaning out of square. FIG. 6 is a partial perspective view of a partially assembled gondola shelving unit 600 including a horizontal platform 601 coupled to one of the first and second uprights 202, 204. The horizontal platform 601 is sized for power cords and electrical wiring and form a power supply platform. In the present example, the horizontal platform 601 is coupled to the central channel of the first and second uprights 202, 204 adjacent the top end 212. Illustrated in FIG. 6 is a possible fourth step of assembling the gondola shelving unit 102 of FIG. 1. The fourth step can include installing the horizontal platform 601 to both the first and second uprights 202, 204. As illustrated in FIG. 6, the horizontal channel 601 is removably coupled with the first and second uprights 202, 204 in a similar manner as described in connection with the cross braces 302, 304 and shown in FIG. 4. For example, the center channel 222 may include a bracket 602 and the horizontal channel 601 includes a tab 604 configured to engage the bracket 602. In various examples, the bracket 602 and tab 604 engage each other similar to the bracket 402 and tab 404 as described in connection with FIG. 4. FIG. 7 is a perspective view of a partially assembled gondola shelving unit 700. The partially assembled gondola shelving unit 700 further includes a back sway brace 706 the first and second uprights 202, 204 being coupled together with the back sway brace 706. Illustrated in FIG. 7 is a possible fifth step of assembling the gondola shelving unit 102 of FIG. 1. The fifth step can include installing the back sway brace 706 to both the first and second uprights 202, 204. As illustrated in FIG. 7, the back sway brace 706 is removably coupled to the central channel 222 of the first and second uprights 202, 204 and adjacent the top end 212. In the present example, the back sway brace 706 includes teeth 708 (such as L-teeth) to engage slots 712 disposed in the central channel 222. In contrast to the front sway brace 206, the teeth 708 and the slots 712 are not angled. In the present example, the back sway brace 706 is not needed to secure or stabilize the partially assembled gondola shelving unit 700 because the front sway brace 206 is already sufficiently securing the partially assembled gondola shelving unit 200, 700. However, in other examples, the central channel 222 could include angled slots and the back sway brace 706 could include angled L-teeth (similar to or in lieu of the front sway brace 206 described in connection with FIGS. 2 and 3). Accordingly, the back sway brace 706 couples to the central channel 222 in a manner similar to the front sway brace 206 coupling to the front tube 224. For example, the teeth 708 releasably engage the slots 712 to selectively secure the back sway brace 706 to the central channel 222. FIG. 8 is a perspective view of a partially assembled gondola shelving unit 800. Illustrated in FIGS. 8, 9, and 10 is a possible sixth step of assembling the gondola shelving unit 102. The sixth step includes removably coupling top panel supports 802 to the front and back sway braces 206, 706. In the present example, the gondola shelving unit 102 includes two sets of top panel supports 802, each set including three top panel supports 802. The top panel supports 802 are triangular structural members that provide a surface on which panels can rest (described in greater detail in connection with FIG. 17). In some examples, the top panel supports 802 can further add rigidity to the partially assembled gondola shelving unit 800, but in the present example, the front sway brace 206 provides sufficient rigidity for the partially assembled gondola shelving unit 800. FIGS. 9 and 10 illustrate the process of installing the top panel supports 802. As illustrated in FIG. 9, the top panel support 802 is rotated 90 degrees (°) and passed between the front and back sway braces 206, 706. When the top panel support 802 is in the proper position, the top panel support 802 is rotated and engages the front and back sway braces 206, 706 via kerfs 1002 in the top panel support 802 receiving a lip 1004 disposed on the front and back sway braces 206, 706. In various other examples, the top panel supports 802 can be releasably secured with the front and back sway braces 206, 706 in various other manners. For example, the top panel supports 802 can engage brackets on the front and back sway braces, similar to the cross braces 302, 304. FIG. 11 is a perspective view of the partially assembled gondola shelving unit 1100 expanded to incorporate a partially assembled, supplementary gondola shelving unit 1100′. Illustrated in FIG. 11 is a possible seventh step in assembling the gondola shelving unit 102 of FIG. 1. In various examples, the seventh step may be omitted or repeated as many times as desired. In various examples, the gondola shelving unit 102 could be extended to be as long as approximately 40 feet, approximately 60 feet, approximately 80 feet, approximately 100 feet, or more feet. As shown in FIG. 11, the supplementary gondola shelving unit 1100′ is attached to the partially assembled gondola shelving unit 1100 as an assembled unit. Alternatively, the supplementary gondola shelving unit 1100′ can be assembled following the foregoing first through sixth steps already described in connection with FIGS. 2-10. As shown in FIG. 11, the supplementary gondola shelving unit 1100′ includes substantially identical components as the partially assembled gondola shelving unit 1100 and, as a result, similar components are identified with the same reference numbers. FIG. 12 is a perspective view of the partially assembled gondola shelving unit 1200. Illustrated in FIG. 12 is an eighth step includes attaching electrical and lighting channels to at least one of the first and second uprights 202, 204. In the illustrated example, the partially assembled gondola shelving unit 1200 includes both horizontal channels 1202 and vertical channels 1204. Additionally, as shown in FIG. 12, the back sway brace 706 includes an aperture 1206 through which, electrical cables and wiring can pass through. As a result, the combination of the vertical channels 1204, the horizontal platform 601, and the horizontal channels 1202 facilitate providing electrical wires throughout the assembled gondola shelving unit 102 of FIG. 1. FIG. 13 is a perspective view of the partially assembled gondola shelving unit 1300. Illustrated in FIG. 13 is a ninth step of assembling the gondola shelving unit 120 of FIG. 1. As illustrated in FIG. 13, a toe-kick 1302 and a base shelf 1304 are removably coupled to the horizontal struts 226. In the present example, the toe-kick 1302 and the base shelf 1304 provide additional stability to the partially assembled gondola shelving unit 1300. In the present example, the toe-kick 1302 and the base shelf 1304 are coupled to the horizontal struts 226. For example, the toe-kick 1302 includes an end surface 1312 and a tab 1314 to engage the horizontal struts 226 and the front tube 224 (shown in greater detail in the assembled close-up in FIG. 13). In the present example, the tab 1314 loosely engages a slot 1316 in the horizontal struts 226 while the end surface 1312 is spaced apart from the tab to removably secure the toe-kick 1302 to the struts 226. Specifically, the distance between the tab and the end surface 1312 are spaced apart such that the tab 1314 disposed in the slot 1316 on the horizontal strut 226 will cause the end surface 1312 to engage the front tube 224. Additionally or alternatively, the base shelf 1304 also engages and is removably coupled with the horizontal struts 226 and, in some examples, additionally engages the central channel 222. In various examples, the base shelf 1304 may include tabs and engage the horizontal strut (similar to the toe-kick 1302) or may include a tensioned bracket to engage slots disposed in the horizontal strut 226. The tensioned bracket is described in greater detail in connection with FIG. 15. Further, the base shelf 1304 can include teeth to engage slots disposed in the central channel 222. In other examples, the toe-kick 1302 and the base shelf 1304 can engage the horizontal struts 226, the front tube 224, and/or the central channel 222 to provide a shelf surface and also further stabilize the gondola shelving unit 1300. In the present example, the toe-kick 1302 is loosely held on the partially assembled gondola shelving unit 1300. Because the toe-kick 1302 loosely engages the partially assembled gondola shelving unit 1300, if the toe-kick 1302 is struck by a pallet jack or shopping cart, the toe-kick 1302 separates from the gondola shelving unit 1300, 102. As a result, the toe-kick 1302 is not damaged and only requires minimal effort to reassemble with the gondola shelving unit 1300, 102. Typical gondola shelving systems do not allow for toe-kicks that loosely engage the shelving system and, as a result, typical toe-kicks would not readily disconnect from the shelving system and instead, could be dented and damaged. FIG. 14 is a perspective view of a partially assembled gondola shelving unit 1400. Illustrated in FIG. 14 is an alternative ninth step and is interchangeable with the ninth step shown in FIG. 13. For example, as illustrated in FIG. 14, a shelf 1402 is removably coupled with the front tube 224 and the central channel 222. Additionally, as shown in FIG. 14, shelves 1404 are removably coupled with the central channel 222 and, in various examples, do not provide additional rigidity to the gondola shelving units 102, 1400. FIG. 15 is a perspective view of the shelf 1402 of FIG. 14 including a tensioned bracket 1502. As shown in FIG. 15, the tensioned bracket 1502 includes a first and second tab 1504a, 1504b engaging a first and second slot 1506a, 1506b, respectively. In the present example, the tensioned bracket centers the shelf 1402 on the strut 226 and quickly aligns the shelf 1402 with the front tube 224 and the central channel 222. Additionally, the tensioned bracket secures the shelf 1402 into gondola shelving unit 1400. The tabs 1504a, 1504b engage the slots 1506a, 1506b. In the present example, the slots 1506a, 1506b are sized to receive two tabs 1504a, 1504b, each. When two tabs 1504a, 1504b are disposed in each slot 1506a, 1506b, the tabs are pressed against each other and create a locking force that secures the shelf 1402. FIG. 16 is a perspective view of the partially assembled gondola shelving unit 1600 including additional shelves 1602. In the present example, the shelves 1602 provide flat horizontal surfaces to store various products. Alternatively, some of the shelves could be configured to store different items that are best stored on non-horizontal surfaces. For example, the shelves 1404 are configured for storing and presenting wine bottles. As described herein, some of the shelves and other components include L-teeth. The L-teeth is shaped like an “L.” When disposed on a shelf, the L-teeth first extend perpendicularly from the back side of the shelf and the extend parallel with the back surface of the shelf. The perpendicular and parallel portions of the L-teeth form a slit between the shelf and the parallel portion. When the L-tooth is passed into an aperture, for example, in the central channel 222, the slit engages the thickness of the material of the central channel and prevents the shelf from slipping, sagging, or falling from the central channel 222. FIG. 17 is a perspective view of the partially assembled gondola shelving unit 1700 including top panels 1702. Illustrated in FIG. 17 is a possible tenth step of assembling the gondola shelving unit 102 of FIG. 1. For example, the top shelves 1702 can be removably coupled to the front and back sway braces 206, 706 and/or the top panel supports 802. In various examples, the top panels 1702 could include clips to secure the top panel to the front and back sway braces 206, 706, could utilize fasteners, could be magnetically attached to the partially assembled gondola shelving unit 1700, and/or any other way of removably fastening the top panel 1702 to the gondola shelving unit 102. The top panel 1702 could be a plywood or plastic panel sufficient to enclose the top of the partially assembled gondola shelving unit 1700. FIG. 18 is a perspective view of the partially assembled gondola shelving unit 1800 including a plurality of side panels 1802. Illustrated in FIG. 18 is a possible eleventh step in assembling the gondola shelving unit 102 of FIG. 1. The side panels 1802 are sized to extend from the front tube 224 and the central channel 222 and from the top panel 1702 to the horizontal struts 226. In various other examples, the side panels 1802 could be larger or smaller than the side panels 1802 shown in FIG. 18. The side panels 1802 are coupled to the partially assembled gondola shelving unit 1800 via tensioned brackets 1902 shown in FIG. 19. FIG. 19 is a perspective, exploded view of one side panel 1802 including the tensioned bracket 1902. The tensioned bracket 1902 includes two tabs 1904 and is identical to the tensioned bracket 1502 shown and described in connection with FIG. 15. In other examples, the tensioned bracket 1902 could be slightly modified compared to the tensioned bracket 1502. For example, the tensioned bracket 1902 could include more or fewer tabs 1904 or could be differently sized. When the side panel 1802 is coupled with one of the first and second uprights 202, 204, the tensioned brackets 1902 engage both horizontal struts 226. The tensioned brackets 1902 engage first and second slots in the horizontal struts 226. Further, in preferred examples, the tensioned brackets 1902 engage another tensioned bracket (not shown) including tabs also disposed in the slots in the horizontal struts 226. Two tensioned brackets both disposed in the same slot in the horizontal strut 226 causes a friction fit to secure the tensioned bracket to the horizontal strut 226. FIG. 20 is a perspective view of a partially assembled gondola shelving unit 2000 including an end cap frame 2002. Illustrated in FIG. 20 is an optional twelfth step of assembling the gondola shelving unit 102 of FIG. 1. In some examples, the end cap shelving unit 104 is not including in the gondola shelving unit 102. Alternatively, the gondola shelving unit 102 could include two end cap shelving units 104. The twelfth step includes coupling an end frame 2010. The end cap frame 2002 includes two vertical supports 2012 and three horizontal struts 2014. The end cap frame 2002 includes two base legs 2016 and four adjustable feet 2018. In the present example, the two vertical supports 2012 are rigidly secured together via the horizontal struts 2014. Additionally, the end frame 2010 is coupled to the rest of the partially assembled gondola shelving unit 2000 via brackets (discussed in greater detail in connection with FIG. 21. Further, the base legs 2016 may be rigidly coupled to the vertical supports 2012, in some examples, the base legs 2016 include L-teeth to engage slots disposed in the vertical supports 2012. FIG. 21 is a perspective view of a bracket 2102 of the partially assembled gondola shelving unit 2000 coupling the end cap frame 2002, via the clip 2104 on the horizontal strut 2014, to the partially assembled gondola shelving unit 2000 of FIG. 20. In various examples, the clip 2104 could rest on the bracket 2102 and/or could partially clamp onto the bracket 2102. As a result, in various examples, the end cap frame 2002 could be loosely held on or securely attached to the partially assembled gondola shelving unit 2000. FIG. 22 is a perspective view of the partially assembled gondola shelving unit 2200 including an optional end cap frame extension 2202. The end cap frame extension 2202 vertically extends above the top of the top panels 1702. In some examples, the end cap frame 2002 does not include the end cap frame extension 2202 and the end cap frame 2002 is completed when panels 2206 are inserted into the end cap frame 2202. The end cap frame extension 2202 is configured to couple to the end cap frame 2002. The end cap frame extension 2202 includes vertical supports 2212 and horizontal struts 2214. In the present example, the vertical supports 2212 and the horizontal struts 2214 are rigidly secured together. The vertical supports 2212 include a column 2215 configured to be inserted into and removably coupled to the vertical supports 2012. The length of the column 2215 is adapted to provide stability to the end cap frame extension 2202. In the present example, the end cap frame 2002 and the end cap frame extension 2202 may include U-channels to receive and secure panels 2206 and 2216 FIG. 23 is a partial perspective view of the gondola shelving unit of FIG. 22 including a foot cover 2302 and a base shelf 2304. FIG. 23 illustrates a possible thirteenth step in assembling the gondola shelving unit 102 of FIG. 1. In the thirteenth step, the foot cover 2302 and the base shelf 2304 stabilize and secure the end cap frame 2002. The foot cover 2303 and the base shelf 2304 prevent the end cap frame 2002 from falling out of the square. Similar to the toe-kick 1302 and the base shelf 1304 described in connection with FIG. 13, the foot cover 2302 and the base shelf 2304 may removably couple to slots disposed in the base legs 2016. In some examples, the end cap frame 2002 is finished by adding a plurality of shelves (as shown in FIG. 1). The shelves disposed on the end cap frame 2002 could be any type of shelf and coupled to the two vertical supports 2012 via, for example, L-teeth on the shelves inserted into slots in the vertical supports 2012. FIG. 24 is a perspective view of the partially assembled gondola shelving unit 2400 including a horizontal channel cover 2402. As described herein, the horizontal channel 601 (of FIG. 6) includes the platform 601 and the horizontal channel cover 2402 enclosing the platform 601. Coupling the horizontal channel cover 2402 to the horizontal channel 601 could comprise an example fourteenth step of assembling the gondola shelving unit 102 of FIG. 1. The horizontal channel cover 2402 covers and protects electrical wires and cords disposed on the platform 601. Accordingly, in preferred examples, coupling the horizontal channel cover 2402 to the partially assembled gondola shelving unit 2400 is a final step after confirming the electrical wiring and shelving lighting are properly installed. Further, the horizontal channel cover 2402 provides a uniform top surface to provide an additional storage surface and store products not yet displayed in the gondola shelving unit 102 of FIG. 1. In various examples, the top surface of the gondola shelving unit can store hundreds or even thousands of pounds of additional product. In accordance with the present disclosure, the gondola shelving unit described herein provides many benefits over typical retail shelving designs. First, the gondola shelving unit is removably coupled without the use of tools to fasten the components of the gondola shelving unit together. For example, coupling the front sway brace to a first and second upright is sufficient make the gondola shelving unit rigid enough to hold and store products for sale. The first and second uprights and the front sway brace coupled together provide sufficient rigidity to the gondola shelving unit to store very large amounts of products that weight. Additionally, because the components of the gondola shelving unit couple together without the use of other fasteners, assembling the gondola shelving unit is easier than typical retail shelving assemblies. In some examples, assembling the gondola shelving unit described in accordance with the present disclosure is quicker than assembling typical gondola shelving units while including additional features such as channels for electrical and lighting accessories. Further, because the front sway brace coupled to the first and second uprights is sufficient to provide all necessary rigidity for storing large amounts of product, the toe-kick is able to loosely engage the first and second uprights. This protects the toe-kick from damage when brought into contact with a pallet jack or a shopping cart. Other shelving systems rely on the toe-kick being securely fastened together and, thereby, susceptible to damage. The foregoing benefits are described by example and do not enumerate all the benefits the presently disclosed gondola shelving unit provide over typical retail shelving assemblies. Those skilled in the art will recognize that a wide variety of modifications, alterations, and combinations can be made with respect to the above described examples without departing from the spirit and scope of the invention(s) disclosed herein, and that such modifications, alterations, and combinations are to be viewed as being within the ambit of the inventive concept(s).
