ENH: provide MPI native minOp, maxOp reduce multiple values

Browse Source 
- consistent with sumOp

ENH: globalIndex with gatherNonLocal tag, and use leading dispatch tags

- useful for gather/write where the master data can be written
 separately.  Leading vs trailing dispatch tags for more similarity to
 other C++ conventions.
