Use of cached adjacency matrix in all algorithms

[sbaldu]

Since we now have a cachedAdjacencyMatrix member, wouldn't it be better to use it in all the algorithms, instead of calling the getAdjMatrix method? I think that in some applications this would save a lot of time, especially for very large graphs.

It absolutely would. I encourage we replace all usages with utilized the cached adj matrix.
