class MGraph[TLabel] extends Graph[TLabel] with Cloneable
The MGraph class stores vertex/edge-labeled multi-directed graphs using
an adjacency set 'ch' representation, e.g., 'ch = { {1, 2}, {0}, {1} }' means
that the graph has the following edges { (0, 1), (0, 2), (1, 0), (2, 1) }.
Optionally, inverse adjacency via the 'pa' array can be stored at the cost
of nearly doubling the storage requirements.
