// Package:     DChain
// Module:      MutableReferenceHolder
// 
// Description: Smart pointer for classes that inherit from ReferenceCount and who can be modified
//
// Usage:
//   This class wraps a pointer to a class inheriting from ReferenceCount
//     and deals with proper handling of the reference counting used to
//     manage the objects lifetime
//
//   MutableReferenceHolder<Foo> pFoo = new Foo;
//   pFoo->bar();
//   takeReferenceToFoo( *pFoo);
//   takePointerToFoo( pFoo.pointer() );
