/** \class TGTreeTable

TGTreeTable is a TGTable that owns it's own interface.
It can be used to view a TTree. If an expression is given to the
constructor, it will be used to define the columns. A selection can
also be given. This selection is applied to the TTree as a
TEntryList. See the documentation of TGTable for more information

The interface is accesible after the creation through the
GetInterface() method.
