I added a DataArray's method expand_dims based on the discussion in #1326 . The proposed API is similar to numpy.expand_dims and slightly different from Variables.expand_dims, which requires whole sequences of dims of the result array.

My concern is that I do not yet fully understand the lazy data manipulation in xarray. Does Variable.expand_dims do it?
