Simplicial elements
===================

Simplicial elements are templated by their dimension.  Simplicial
elements of dimension :math:`d` (edges in 1D, triangles in 2D and
tetrahedra in 3D) are modelled as static arrays of :math:`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.
