1. An apparatus comprising:
a base;
a pair of walls that extend upwardly from the base, wherein the pair of walls are elongate along a first axis, wherein the pair of walls are parallel or generally parallel to each other, wherein each wall of the pair of walls defines an upper end, an inner surface, and an outer surface;
a plurality of transverse members having a respective first end and a second end that are spaced along a second axis that is perpendicular to the first axis, wherein each transverse member of the plurality of transverse members comprises:
a top surface;
a bottom surface that is spaced from the top surface along a vertical axis that is perpendicular to each of the first axis and the second axis;
a respective first downwardly extending projection and second downwardly extending projection at each end of the first end and the second end, wherein the respective first downwardly extending projection and second downwardly extending projection are spaced from each other along the second axis, wherein the upper end of a respective wall of the pair of walls is received between the respective first downwardly extending projection and second downwardly extending projection; and
at least one receiving slot disposed between the top surface and the bottom surface, wherein each transverse member of the plurality of transverse members has a width between a first side and a second side that are spaced along the first axis, wherein the at least one receiving slot comprises:
a first receiving slot that extends inwardly from the first side through only a portion of the width of said transverse member; and
a second receiving slot that extends inwardly from the second side through only a portion of the width of said transverse member.
