sagemath_rankwidth: Rankwidth and rank decompositions of graphs with rw¶

This pip-installable distribution passagemath-rankwidth is a small optional distribution for use with passagemath-graphs.

It provides a Cython interface to rw by Philipp Klaus Krause, which calculates rank width and rank decompositions.
