//~ Methods ----------------------------------------------------------------
/**
* Generate a graph structure. The topology of the generated graph is
* dependent on the implementation. For graphs in which not all vertices
* share the same automorphism equivalence class, the generator may produce
* a labeling indicating the roles played by generated elements. This is the
* purpose of the resultMap parameter. For example, a generator for a wheel
* graph would designate a hub vertex. Role names used as keys in resultMap
* should be declared as public static final Strings by implementation
* classes.
*
* @param target receives the generated edges and vertices; if this is
* non-empty on entry, the result will be a disconnected graph since
* generated elements will not be connected to existing elements
* @param vertexFactory called to produce new vertices
* @param resultMap if non-null, receives implementation-specific mappings
* from String roles to graph elements (or collections of graph elements)
