dev-python/networkx: Added.

NetworkX, a Python-centric graph theoretic framework, is now available
as both live (i.e., 9999) and stable (i.e., 2.1) ebuilds. While official
Portage ebuilds of NetworkX also exist, they are painfully obsolete as
of this writing.

+    NetworkX is a Python-based package for the creation, manipulation, and
+    study of the structure, dynamics, and functions of complex networks.
+    The structure of a graph or network is encoded in the edges (connections,
+    links, ties, arcs, bonds) between nodes (vertices, sites, actors). If
+    unqualified, by graph we mean a simple undirected graph, i.e. no
+    self-loops and no multiple edges are allowed. By a network we usually
+    mean a graph with weights (fields, properties) on nodes and/or edges.
+    The potential audience for NetworkX includes: mathematicians, physicists,
+    biologists, computer scientists, social scientists.
