Class Description

                                                                      
 This class registers all instances of TObject and its derived        
 classes in a hash table. The Add() and Remove() members are called   
 from the TObject ctor and dtor, repectively. Using the Print()       
 member one can see all currently active objects in the system.       
 Using the resource (in .rootrc): Root.ObjectStat one can toggle this 
 feature on or off.                                                   
 Using the compile option R__NOSTATS one can de-active this feature   
 for the entire system (for maximum performance in highly time        
 critical applications).                                              
                                                                      
 The following output has been produced in a ROOT interactive session
 via the command gObjectTable->Print()

 Create an object table.

 Delete TObjectTable.

 Print the object table.

 Add an object to the object table.

 Add an object to the global object table gObjectTable. If the global
 table does not exist create it first. This member function may only
 be used by TObject::TObject. Use Add() to add objects to any other
 TObjectTable object. This is a static function.

 Delete all objects stored in the TObjectTable.

 Remove an object from the object table.

 Remove an object from the object table. If op is 0 or not in the table
 don't complain. Currently only used by the TClonesArray dtor. Should not
 be used anywhere else, except in places where "special" allocation and
 de-allocation tricks are performed.

 Deletes the object table (this static class function calls the dtor).

 Find an object in the object table. Returns the slot where to put
 the object. To test if the object is actually already in the table
 use PtrIsValid().

 Rehash the object table in case an object has been removed.

 Expand the object table.

 Print the object table.

 Histogram all objects according to their classes.

 Issue a warning in case an object still appears in the table
 while it should not.
