What methods and properties must be implemented in DataArray to assure it works properly?  Is there a full template/example of doing this?

#### Problem description

Hello,

I created a custom Series in pandas' that has function on it not normal to a normal pd.Series.  Can you create custom columns in xarray?  Are there any examples of that?
