Class Description

 TVirtualBranchBrowsable is a base class (not really abstract, but useless
 by itself) for helper objects that extend TBranch's browsing support.
 Each registered derived class's generator method is called, which fills
 all created helper objects into a list which can then be browsed.
 For details of what these browser helper objects can do, see e.g.
 TMethodBrowsable, which allows methods to show up in the TBrowser.

 Only registered helper objects are created. By default, only
 TMethodBrowsable, TNonSplitBrowsable, and TCollectionPropertyBrowsable
 are registered (see RegisterDefaultGenerators). You can prevent any of
 their objects to show up in the browser by unregistering the generator:
   TMethodBrowsable::Unregister()
 will stop creating browsable method helper objects from that call on.
 Note that these helper objects are cached (in TBranch::fBrowsables);
 already created (and thus cached) browsables will still appear in the
 browser even after unregistering the corresponding generator.

 You can implement your own browsable objects and thier generator; see
 e.g. the simple TCollectionPropertyBrowsable. Note that you will have
 to register your generator just like any other, and that you should
 implement the following methods for your own class, mainly for
 consistency reasons:
   static void Register() {
     TVirtualBranchBrowsable::RegisterGenerator(GetBrowsables); }
   static void Unregister() {
     TVirtualBranchBrowsable::UnregisterGenerator(GetBrowsables); }
 where GetBrowsables is a static member function of your class, that
 creates the browsable helper objects, and has the signature
   static Int_t GetBrowsables(TList& list, const TBranch* branch,
                              const TVirtualBranchBrowsable* parent=0);
 It has to return the number of browsable helper objects for parent
 (or, if NULL, for branch) which are added to the list.

 Browses a TCollectionPropertyBrowsable. The only difference to
 the generic TVirtualBranchBrowsable::Browse is our fDraw

 If the element to browse (given by either parent of branch) contains
 a collection (TClonesArray or something for which a TVirtualCollectionProxy
 exists), we will add some special objects to the browser. For now there is
 just one object "@size", returning the size of the collection (as in
 std::list::size(), or TClonesArray::GetEntries()).
 The objects we create are simply used to forward strings (like "@size") to
 TTreeFormula via our Browse method. These strings are stored in fName.
