I suggest that when you want to treat your object `dw::DataFramesWrapper`  
as a DataFrame, that you just do:  
`dw.df` and work with the `DataFrame` field directly.

Invenia has a a package that subtypes DataFrames, and its just a bit much maintance work for too little gain, so we are looking to retire it.
