----------------------------+-----------------------------------------------
In many algorithms we want to find a random vertex or a random edge in a
graph. It is also very often required to find, given a vertex, one edge
adjacent to it ( for example in depth first or breadth first search ).
This should be possible easily, and most importantly efficiently ( if
possible, directly written in C ) as DFS and BFS are very slow when
written in python ( same problem with Floyd Warshall for
all_pairs_shortest_path and networkX's distance function )
