CQ3ObjectRef

Wrapper for Quesa objects.

The main purpose for using a C++ wrapper for a Quesa object is to prevent memory leaks. The wrapper's destructor disposes the object. This class is designed to be usable in STL container classes. It is not like std::auto_ptr, in that the copy constructor adds a reference rather than transferring ownership. One could base such a wrapper on boost::intrusive_pointer, but I chose not to require Boost.

Due to a HeaderDoc bug, it is not possible to automatically document more than one constructor. Besides the constructor from a TQ3Object, there is a default constructor (which holds NULL) and a copy constructor.

This wrapper is not fully functional with objects that are not reference-counted (such as views and picks) because the copy constructor calls Q3Shared_GetReference.
