3357	csr assign method not working with undirected graphs	sebastian.weber@…	Andrew Sutton	"Hi!

Assigning an undirected graph to a csr graph results in an ill defined object. Example:

UndirAdjacencyListGraph adjGraph;

CsrGraph csr;

csr.assign(adjGraph);

This will result in an ill defined csr graph, but with the trick of doubling the edges nominally, everything works as it should:

csr.assign(adjGraph, vertexIndex, num_vertices(adjGraph), 2*num_edges(adjGraph));

works perfeclty and returns a csr graph where the undirected links have been replaced by 2 directed edges appropietly.
