Grid/Grid_comparison.h
Peter Boyle 31f4f4f1e1 "where" and integer comparisons logic implemented for conditional
assignment. LatticeCoordinate helper to get global (reduced) coordinate.

Some more work of similar type perhaps needed, but the bulk of the required
structure for masked array assignment is now in place.
