1. The RooAbsDataStore has a virtual function `tree()` which is not meaningful for a general data store. This function should be removed. 2. The RooTreeDataStore has one `const` version on `tree()` and one non-const version. One returns a pointer and the other a reference, which is very confusing. 3. The RooTreeDataStore has some methods that just forward to the underlying TTree, but they were not used. Changes to the data store classes can be made without impacting users because they are implementation details of the RooFit dataset classes.
Using this function is introducing memory leaks too easily if used wrong, because it returns a `RooArgsSet *` that needs to be deleted by the caller without documenting this. This commit suggests to simply remove this function, after all one could just call `addColumn()` in a loop and be safe.
