#229 fixed Default implemention of Tolerace<> is faulty Alpar Juttner Alpar Juttner
Description

The default implementation of Tolerance<> is faulty (it answers false to everything). Probably, it should not exist at all except the documentation.

#230 fixed Faulty check whether 'long long' is available in tolerance.h Akos Ladanyi Alpar Juttner
Description

The current check

#if defined __GNUC__ && !defined __STRICT_ANSI__

evaluates to false somehow (using autotools' default settings)

It would be nice if we had a reliable HAVE_LONG_LONG define which could be used throughout the library.

#231 fixed readDimacsMat() should (also) read undirected graph Alpar Juttner Alpar Juttner
Description

Currently, all DIMACS reader creates directed graphs. So does readDimacsMat(), though here the undirected graph would be the natural choice. (The DIMACS MAT format is for the maximum matching problem).

On the other hand, the MAT format is also perfectly usable for storing a directed graph. Therefore we should make it possible to read a MAT file to a Digraph, too.
