Detailed Description

This is a convenience class used in symmetrizeFootprint, wrapping the idea of iterating through a SpanList either forward or backward, and looking at dx,dy coordinates relative to a center cx,cy coordinate.

This makes the symmetrizeFootprint code much tidier and more symmetric-looking; the operations on the forward and backward iterators are mostly the same.
