Detailed Description

template<typename INDX = uint>
class simplexD1linked< INDX >

A instance of a generalized simplex in 1D.

The neighbor link is defined : given neighbor k, the point opposite and hence not in contact with the neighboring simplex k has a local index which is the index to neigbor k.

This definition was choosen because it generalized to simplexes in any dimension, and is useful in algorithms. ie piInverse.
