Introduce unweighted bipartite matching problem

[rluce]

• Input sparse graph / matrix (whatever scikit learn uses)
• Pics

Where are we standing on this mod? The current look and feel is a lot like work in progress...

• It goes by the name "Maximum Weighted Matching" but we still restrict it to bipartite
• Documentation has boiler plate text blocks in it

Is the plan to polish it up to a proper mod, or to shelve it ?

Unweighted bipartite matching is almost done (I have a branch still to merge). General weighted matching (#12) is far from complete, might shelve it for the first release since we have plenty of graph mods.

This is done, closing
