Each of the contiguous sidewalls abuts the perimeter, andcollectively the contiguous sidewalls abut the perimeter in its entirety. Adjacent pairs ofthe contiguous sidewalls abut each other along respective corner edges. The
multifaceted surface is spaced apart from the base surface by the contiguous sidewalls.At least one V-shaped groove extends from one of the corner edges across themultifaceted surface to one of the contiguous sidewalls that does not contact thatcorner edge.
