TTreeTableInterface is used to interface to data that is stored in a TTree.

When the interface is created, an expression can be specified. This expression will define the columns to be shown.

A selection criterium can also be specified. A TEntryList will be created and applied to the TTree using this criterium. a new TEntryList to use can be specified using SetEntryList. TGTable->Update() will need to be called to show the effects.

WARNING: Do not apply an entrylist to the tree in any other way than through the interface, this will have undefined consequences.

Columns can be manipulated using the appropriate methods. A TGTable->Update is always needed afterwards to make the table aware of the changes.
