class TVirtualBranchBrowsable: public TNamed

 constructor setting all members according to parameters.

 Destructor. Delete our leaves.

 Calls TTree::Draw on the method if return type is not a class;
 otherwise expands returned object's "folder"

 Askes all registered generators to fill their browsables into
 the list. The browsables are generated for a given parent,
 or (if 0), for a given branch. The branch is passed down to
 leaves of TVirtualBranchBrowsable, too, as we need to access
 the branch's TTree to be able to traw.

 Check whether the branch (or the parent) contains a collection.
 If it does, set "contained" to the contained type (if we can
 retrieve it) and return the TClass for the collection. Set
 "contained" to the branch's (or parent's) contained object's
 class for non-collections, returning 0.

 Only one of "branch" or "parent" can ge given (depending on whether
 we are creating browsable objects for a branch or for another
 browsable object)

 Return list of leaves. If not set up yet we'll create them.

 Returns the full name for TTree::Draw to draw *this.
 Recursively appends, starting at the top TBranch,
 all method / object names with proper reference operators (->, .)
 depending on fTypeIsPointer.

 Adds the default generators. The user can remove any of them as follows:
   TMethodBrowsable::Unregister();
 which will cause the browser not to show any methods.

 Adds a generator to be called when browsing branches.
 Called by the Register method, which should be implemented
 for all derived classes (see e.g. TMethodBrowsable::Register())

 Removes a generator from the list of generators to be called when
 browsing branches. The user can remove any of the generators as follows:
   TMethodBrowsable::Unregister();
 which will cause the browser not to show any methods.
