public class PbPyramidCell
extends PbCell
implements java.lang.Cloneable

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
