fix "ValueError: max()" in LPA.get_max_neighbor_label()
f69dd88 
max(m.itervalues()) will raise ValueError when calling LPA.get_max_neighbor_label()
with a parameter isolated vertex, which has no neighbors.
It is reasonable to return label of the vertex itself if it's an isolated vertex.

I meet the same problem when I use club dataset. However, when I use my own dataset, it works. Do you know why? Thanks

@XiaosongLis There should be no isolated vertices in your dataset, please see #10 (fixed this bug) for details.
