Draw bug

[tacaswell]

The documentation claims that node labels are not drawn. Modified the plotting code so this is actually true.

@hagberg This broke back-compatibility with out documentation (see http://stackoverflow.com/questions/25865975/pylab-networkx-no-node-labels-displayed-after-update).

What do you want me to do to fix it?

[tacaswell]

Actually reading back into this a bit more, I seems that this brought the behaviour in line with the documentation, not the other way around.

Maybe it should be extended so that if labels is a kwarg, then with_labels is automatically set to True? This seems more in line with what the user actually intends---as there is never a time when it is useful to pass in labels and have with_labels be False. When labels is None, then if the user wants the "default" labels, then they must explicitly pass with_labels=True (this is the current situation and should remain).

[tacaswell]

Something like

if 'with_labels' not in kwds:
   kwds['with_labels'] = 'labels' in kwds

which will never over-ride explicit user input, but will add the labels if they are explicitly passed in?

[tacaswell]

And I can image cases where you would want to pass in both labels and with_labels=False if you are using draw in a higher level function that adds custom labels, but still makes it possible to toggle drawing them with a flag.

Ah yes, I suppose that is true. You might not remove it from kwargs and so you want some way of turning it off. What you proposed sounds good to me.
