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

- called to produce new verticesresultMap
- if non-null, receives implementation-specific mappings
from String roles to graph elements (or collections of graph
elements)
