source: trunk/test/graph.cc @ 1194

Last change on this file since 1194 was 1194, checked in by Peter Johansson, 10 years ago

refs #475. First version using Sparse Vector class. This change is obviously quite invasive and thus the size of this commit is larger than what is preferred. I've tried to limit as much as possible and left optimization and style issues behind with a note 'FIXME'.
