Using bathymetry.py create a simple unit test with child grid as a 1:1 sub region of the parent (i.e. longitude, latitude, depth grid points are all colocated)
[x] Parent dx/dy 1\deg, -20E:10E, 45N:65N
[x] Child dx/dy 1\deg, -10E:0, 50N:60N
[x] Depth levels 50:5000:100 using the flat bottom case
[ ] Generate constant variables
Test success: output files match subset of Parent data
