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:
 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.
void Browse(TBrowser *b)
 Browses a TCollectionPropertyBrowsable. The only difference to
 the generic TVirtualBranchBrowsable::Browse is our fDraw
Int_t GetBrowsables(TList& li, const TBranch* branch, const TVirtualBranchBrowsable* parent /* =0 */)
 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.
void Register()
 Wrapper for the registration method. Needed against MSVC, which 
 assigned different addr to the same method, depending on what
 translation unit you're in...
void Unregister()
 Wrapper for the registration method. Needed against MSVC, which 
 assigned different addr to the same method, depending on what
 translation unit you're in...
const char* GetDraw()
 return the string passed to TTree::Draw
TCollectionPropertyBrowsable(const char* name, const char* title, const char* draw, const TBranch* branch, const TVirtualBranchBrowsable* parent=0)
 contrsuctor, which sets the name and title according to the parameters
 (and thus differently than our base class TVirtualBranchBrowsable)
