Script to append MPAS mesh information

[sbrus89]

@xylar, I recently wrote a really simple script that appends MPAS mesh variables from one file to another (e.g.,input.nc to output.nc) using ncks. I needed it to be able to easily import a MPAS-O output file (that didn't contain mesh information) into paraview. I thought I'd ask if a) you think this is a useful script to commit somewhere and b) if you think MPAS-Tools is the right place. Maybe something like this already exists?

Yes, MPAS-Tools is the right place for such a script.

I don't personally need that because I always use the paraview_vtk_extractor tool, which can point separately to an input and a mesh file. I don't like the way Paraview displays MPAS data by default. But it certainly could be that others could use such a tool. Go ahead and make a PR if you like.
