Support for establishing and maintaining graph element equivalence (such as in blockmodeling).
In blockmodeling, groups of vertices are clustered together by similarity
(as if members of a "block" appearing on the diagonal of the graph's adjacency
matrix).
This support currently includes:
VertexPartition
: A class that maintains information on a
division of the vertices of a graph into disjoint sets.
StructurallyEquivalent
: An algorithm that finds sets of vertices that are
structurally equivalent.
