.csv data output

[dmragar]

Royal would like time series .CSV data outputs. The data should show WPU change over time for all veg types. They showed an example with individual pixels flattened w/ index values for location, as well as a column of WPU membership for pixel.

We can start building a CSV output function, and then refine as they/we get a better sense of the specs.

This could use np.savetext (simplest) or possibly use the existing VegTransition._save_state_vars() to build up an xarray Dataset, which would have a .to_pandas() method that could be very handy for better formatting control. We also still need to output .tifs or .NetCDF for Cam, so this is probably the way to go.

In progress #16

this code will be independent of VegTransition (i.e. a post-processing step, where reading the VegTransition files into a xr.Dataset is the first step.

Update: there are now two .csv outputs for VegTransition. A domain-wide pixel count, and a WPU-specific count.

VegTransition.post_process()
