Hi,
I have a graph defined as follow:

struct NodeData{ /*...*/ };
struct EdgeData{ /*...*/ };
typedef adjacency_list<setS, setS, undirectedS, NodeData, EdgeData> MyGraph;
MyGraph G;

This graph is updated iteratively (by adding/deleting some edges/vertices).
At each iteration, I want to evaluate the memory space occupied by this
graph G. How can I do that ?
