group local indices from the rank's support into n groups or "bins" (some possibly empty) according to which of the n image indices they are mapped to on this rank. The groups are concatenated and returned as a single array. See <A HREF="../DM/SAMappingBinSplit.html#SAMappingBinSplit">SAMappingBinSplit</A>() if separate bin output is desired. Since SAMapping is potentially multivalued, the same index can appear in multiple bins. The binning is done only on the indices of the selected type (I or J); the other indices and weights, if any, are moved to the appropriate bin together with the selected indices.
