OrthogonalMultidimensionalProfile from_dataframe raises NotImplementedError

[eldobbins]

I'm trying to write several CTD casts into a single netCDF file. This is following NCEI_Profile_Orthogonal. The data are in a single Pandas Dataframe with columns for pressure (z) and cast number (profile). However, from_dataset doesn't seem to exist..

I also have an issue with IncompleteMultidimensionalProfile, and submitted a separate ticket for that. (#52)

OrthogonalMultidimensionalProfile isn't implemented. Can you use IncompleteMultidimensionalProfile?

I'm planning to set aside some time in early July to implement OrthogonalMultidimensionalProfile.from_dataframe. With 2 years more experience, I'm pretty sure I can do it.

For testing, I'd like to convert the netCDF files are that already in tests/dsg/profile/resources/ to CSV to see if I can regenerate the original netCDF files. So I would use Xarray and Pandas to write the data from om-multiple.nc and om-single.nc into CSV files. Then I'll transfer the attributes into a JSON file. Then in test_profile_om.py, I'll combine those and compare the result using the is_mine method that is already in om.py

If all goes well, I should have material for another Notebook to add to the documentation too.

Let me know if this sounds like the wrong approach.
