I often want a function that takes a dataarray / dataset and replaces a dimension with a coordinate from a different dataset.

@shoyer proposed the following simple solution. ```python def replace_dim(da, olddim, newdim): renamed = da.rename({olddim: newdim.name})

# note that alignment along a dimension is skipped when you are overriding
# the relevant coordinate values
renamed.coords[newdim.name] = newdim
return renamed

```

Is this of broad enough interest to add a build in method for?
