Collective on A.
Notes: observe that each local support index might be mapped to the same global index multiple times, if it happens to have the same number within different bins. In order to decide which color each of the new numbers refers to, it is useful to use the result B in conjunction with the original pseudograph A as the second and first argument to MatIJBinMap(), respectively. By construction, B is compatible to A in the sense of MatIJBinMap().
