class gedge
this class defines general edge, which can be used in connection with general finite elements only topological informations are collected
the class is motivated by solution of hemivariational inequalities, in 2D problems, there is a contact between two parts of a body matching mesh is assumed and therefore two elements share one edge, the edge has to know four nodes because it will work with differences of displacements
example:
BODY 1 3 4 5 ---2-------3--------4--------5---- ---6-------7--------8--------9---- 2 3 4 BODY 2
edge 4 from the body 1 and edge 3 from body 2 are identical, they are stored in one general edge which has to know nodes 3,7,4,8 nodes in body 1 are ordered first, nodes in body 2 are ordered after ordering of body 1 number of nodes on edge nn=4 node multiplicity nm=2 list of nodes on edge nlist[0]=3, nlist[1]=7, nlist[2]=4, nlist[3]=8
