Replace input currents as (mag, dir) to (u, v)?

[ekrell]

Currently the input rasters are in form magnitude & direction.

Better to use u and v vector components?

• Typical ocean model output
• Don't have to worry about if the directions are radians or degrees.

At one point the code did use u and v. In fact, the source code variable names are still currentsGrid_u and currentsGrid_v inside planners/metaplanner.py... even though it is actually performing calculations assuming they are magnitude and direction.
