[igraph] basic graph construction

[Kurt J]

Hi List,

This is a very basic question i can't seem to figure out from the API
docs.  I'm using the python interface to analyze a social graph.  In
my data, each vertex is represented by an UID.  I'm not clear how to
associate a UID w/ a vertex in igraph.

>>> g = igraph.Graph(directed=True)
>>> g.add_vertices(1)

Then how can i access that vertex object to add a UID attribute?  Or
is there a better way?

Previously i was using networkx which had a nice syntax allowing each
node to be named as you want.  But nx did not seem to scale well
enough...

Thanks,
Kurt J
