Various kinds of branches can be added to a tree:
A - simple structures or list of variables. (may be for C or
Fortran structures)
B - any object (inheriting from TObject). (we expect this
option be the most frequent)
C - a ClonesArray. (a specialized object for collections of
same class objects)

My question is: must object inherit from TObject? Or is it sufficient
that they be ClassDef'ed and ClassImp'ed?

If they must be derived from TObject, then I assume I am forced to use
Case A and list out every field I want as a TTree branch.
