New description:
Hello everybody !
This patch is an interface between Sage and the software RW, written by
Philipp Klaus Krause [1]. It is written in C, and freshly licensed under
the GPL2. It is a highly enumerative code that uses a lot of memory, but
is still so far the best practical way to obtain optimal decompositions.
This patch creates the module sage.graphs.graph_decompositions and the
rankwidth-related files. As it requires some documentation, some words are
added on what a rank-decomposition is and where the code is coming from.
Doing that, I also added sage.graphs.modular_decompositions to the
documentation.
(As I created a module graph_decompositions, it would make sense to move
te modular_decomposition there. It thought it best to do it in a distinct
patch, this one being large enough already)
Oh. By the way, most of the patch actually contains the copy of the files
written by Philipp Klaus Krause.
