Print training progression (node2vec)?

[ldorigo]

Hi, is there any way to monitor training progression? Even with verbose=True, nothing gets printed out after "Mapping Walk Names... Done" (and if the training can be expected to take several hours, it's a bit annoying to have no idea if anything is actually happening).

It could be difficult to add something like a tqdm progress counter to these loops, because most of the hot loops in node2vec are lower level (either compiled numba stuff, or a pandas map applied).

Ill try to see where it's possible to do in node2vec
