Simplicial elements

Simplicial elements are templated by their dimension. Simplicial elements of dimension \(d\) (edges in 1D, triangles in 2D and tetrahedra in 3D) are modelled as static arrays of \(d+1\) pointers to objects of type R3.

By convention, within an element, the vertices are systematically arranged in ascending order of their adress. As a consequence, two elements cannot differ only by a permutation of their vertices.
