Defines a pyramid cell of a volume mesh.
A pyramid cell has 5 facets which can be in any plane of 3D space. It has 4 triangle facets and 1 quadrangle facet. The 4 first indices define the base quadrangle facet oriented towards the interior of the cell.
Facets, nodes and edges are numbered as follows:
n4 x facet 0 = 0123 edge 0 = 01 /| \ . facet 1 = 041 edge 1 = 12 / | \ . facet 2 = 142 edge 2 = 23 / | \ . facet 3 = 243 edge 3 = 30 / | \ . facet 4 = 340 edge 4 = 04 / | \ . edge 5 = 14 / n3 x------\----------x n2 edge 6 = 24 / ' \ ' edge 7 = 34 / ' \ ' n0 x------------------x n1
