Most implementations will probably want to inherit from the abstract class BaseGraph since it contains reference implementations of various algorithms (Graph Equality/Graph Difference/Sub-Graph testing etc) which will save considerable work in implementation and ensure consistent behaviour of some methods across implementations.
