|mc ||- the MatColoring context
|dist ||- the distance the coloring should compute
The distance of the coloring denotes the minimum number
of edges in the graph induced by the matrix any two vertices
of the same color are. Distance-1 colorings are the classical
coloring, where no two vertices of the same color are adjacent.
distance-2 colorings are useful for the computation of Jacobians.
