Documentation for input dataset requirements / conventions

[darothen]

At the moment, we don't provide any clear documentation on what the structure of input datasets should look like in order to play nicely with EWB:

• What temporal dimensions do we need? For both the forecast lead time and the epoch/init time?
• What should the latitude coordinate be named and should it be ascending or descending?
• What should the longitude coordinate be named and should it run from [0,360) or [-180, 180)?
• What are the standard naming conventions and units expected for fields?

There are probably more details needed, but this information is critical to explicitly lay out so that users can connect EWB to their own datasets.

hi - 
have you considered cf-xarray for this? If there will be documentation, then scripting it as conventions → cf accessor? I also have some other ideas in mind if interested.
