Detailed Description

Facilitates iteration through a multidimension index space. Since there are multiple ways for navigating index space (column- vs. row-major, etc.), this class should be abstract, with an abstract ++ operator. The original IndexIterator assumed the highest dimension (NDIM-1) would be iterated quickest (this index changes each time ++ is called), however, sometimes a different order is desired.

For legacy purposes, operator++ is thus NOT abstract, but has the implementation of the HighDimIndexIterator defined below. Eventually, the IndexIterator::operator++ should be deprecated, and such instances of IndexIterator replaced with HighDimIndexIterator.
