Detailed Description

class to handle inter-process communication of pixel data from non-contiguous regions of a shared index space.

For example copying a subset of one image to a subset of another. The class can be used for purely local(no MPI) non-contigious data transfers by setting the source and destination ranks to the same id. In that case memcpy is used.
