Description
Current support for xarray is fairly primitive. Some features that would be nice are:
- Add support for using xarray.Dataset directly instead of extracting the NetCDF object.
- Being able to subset the Dataset's data prior to reading so the entire array isn't used.
- Some of this may be better handled using input iterables classes as wrappers.
- See also issue #6
- Add multidimensional indexing support by using the latlon_to_xy routines.
- Make isel, sel, and other indexing features work correctly.
This list will be updated as needed.

Research direction
Start by reviewing the existing xarray support and issue #6, then trace the latlon_to_xy routines and current indexing behavior. The work is done when Dataset inputs, pre-read subsetting, multidimensional indexing, and isel/sel behavior are supported correctly.
