As you can guess from the version number this software is
still somewhat unstable. The implementations may be extremely
buggy, the APIs can change. You have been warned.
NOTE: the releases 0.003...0.004 do not contain all the algorithms
that 0.001 (and the never-publicly-released 0.002) had. They are
under reconstruction as the data structures underwent a major overhaul
in 0.003.
