Detailed Description

GeneralizedIndex is a locator for an element in vector with arbitrary block structure. Together with the processor's rank it can uniquely specify an element in a distributed vector. This object is used in operations such as minloc and maxloc on arbitrarily-structured vectors.

The implementation is a simple pair of (1) a deque giving the sequence of block indices and (2) an integer giving the local offset within the lowest-level block. The integer index is local, i.e., relative to the block pointed to by the block index.
