	http://snap.stanford.edu
========================================================================

Stanford Network Analysis Platform (SNAP) is a general purpose, high
performance system for analysis and manipulation of large networks.
SNAP is written in C++ and it scales to massive graphs with hundreds
of millions of nodes and billions of edges.

SNAP Introduction: http://snap.stanford.edu/snap/doc.html

The library defines Graphs (nodes and edges) and Networks (graph with data
associated with nodes and edges).

Graph types:
  TNGraph : 
  	directed graph (single directed edge between a pair of nodes)
  TNEGraph : 
  	directed multi-graph (any number of directed edges between a pair of
	nodes)
  TUNGraph : 
  	undirected graph (single undirected edge between a pair of nodes)

Network types:
  TNodeNet<TNodeData> : 
  	like TNGraph but with TNodeData object for each node
  TNodeEdgeNet<TNodeData, TEdgeData> : 
  	like TNEGraph but with TNodeData object for each node and TEdgeData
	object for each edge
  TBigNet<TNodeData> : 
  	memory efficient implementation of TNodeNet (avoids memory
	fragmentation)
