Not sure if it's worth a separate feature request, but it'd be great to have a drop option in .isel() as well. For example:

``` python

ds <xarray.Dataset> Dimensions: (lat: 360, lon: 720, time: 2928) Coordinates: * lon (lon) float64 0.25 0.75 1.25 1.75 2.25 2.75 3.25 3.75 4.25 4.75 ... * lat (lat) float64 -89.75 -89.25 -88.75 -88.25 -87.75 -87.25 -86.75 ... * time (time) datetime64[ns] 2012-01-01 2012-01-01T03:00:00 ... Data variables: dswrf (time, lat, lon) float64 446.5 444.9 445.3 447.8 452.4 456.3 ...

ds.isel(lat=0, lon=0, drop=True) <xarray.Dataset> Dimensions: (time: 2928) Coordinates: * time (time) datetime64[ns] 2012-01-01 2012-01-01T03:00:00 ... Data variables: dswrf (time) float64 446.5 444.9 445.3 447.8 452.4 456.3 ... ```

This would be useful for making .to_dataframe() more efficient, too, I suspect, since I have to currently do forcing.isel(lat=0, lon=0).to_dataframe()[['dswrf']] to remove the (constant) lat/lon data from the dataframe.
