A first wall (14,15) of the plurality of upright walls (14,15) has a recessed portion (16,17) forming at least a portion to allow extension and contraction in multiple directions of the at least one cell (12). The plurality of upright walls (14,15) of the at least one cell (12) define a perimeter such that the recessed portion (16,17) extends towards a second wall (14,15) of the plurality of upright walls (14,15) and is within the perimeter.</p> |
