//     Function: CPPTypedef::Constructor
//       Access: Public
//  Description: Constructs a new CPPTypedef object based on the
//               indicated CPPInstance object.  The CPPInstance is
//               deallocated.
//
//               If global is true, the typedef is defined at the
//               global scope, and hence it's worth telling the type
//               itself about.  Otherwise, it's just a locally-scoped
//               typedef.
