Hi Michael,

I have just made the modificationis to support other than
curvilinear grid with exch2 and blank tiles.

I have also changed the tiling of verification experiment
"global_ocean.90x40x15" to provide an example and also to test 
this (it's set-up only for MPI built & run, using code/*_mpi 
and input*/*.mpi files, but should work as well without MPI).
