New description:
The additional functionality included in this patch are:
- various possibilities for the tessellation of the fundamental domain
(Dedekind, coset, none)
- membership test via the Lang, Lim, Tan algorithm
- improved LaTeX output (via xymatrix)
- reduction to cusp
- identify cusp class
Added tests for LLT algorithm and reduction to cusp.
