Create PIC algorithm for tx_2_3
-- read tx2_3 grid and look at the calculation
-- Test weight calculation for a randomly angled rectangular grid
-- Create the nearest neighbor search algorithm with the existing grid file. Make it fast.

used by MOM6 for the workhorse 2/3 degree configuration.
You can see how the grid angle is computed internally by MOM6 here
