Title: Change DataFrame to AbstractDataFrame

I didn't see anything in there that was specific to DataFrames. A change to the abstract form should make this more generic. We already have a SubDataFrame that is very useful, so it'd be nice to be able to plot subsets without copying by using this.

As you're looking at faceting, you may want to use `groupby` to generate the groupings, and `groupby` uses SubDataFrames.
