Big changes here:
1. Do the vertical interpolation of the u and v components separately then at the end calculate the depth averaged velocity as well as the depth averaged u and v components into separate fields in Mobj. This is all necessary for outputting the ASCII files for mean flow and the open boundaries. 2. Make the vertical interpolation scale the POLCOMS-ERSEM depth range to match the current FVCOM node's depth range, thus squeezing or stretching the vertical velocity profiles into the FVCOM depth. 3. Add a commented out section which can be used to plot the vertical profiles to make sure they have interpolated correctly.
