class endnode
this class defines end nodes, 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 1D problems, there is a contact between two parts of a body matching mesh is assumed and therefore two elements share one end node, the end node has to know two nodes because it will work with differences of displacements
example:
BODY 1 ---3----4 7----8----12---- BODY 2 3 end node 4 from the body 1 and end node 7 from body 2 are identical, they are stored in one end node which has to know nodes 4, 7 node in body 1 is ordered first, node in body 2 is ordered after ordering of body 1 number of nodes collected in end node is 2
