Refactored the QMF engine to adhere to the following rules regarding

the pimpl (Pointer to Implementation) pattern:

1) Impl classes have constructors matching the public constructors
2) Additional Impl constructors are accessed through a static factory function
3) All linkages to objects are to the public object
4) If a back-link (from Impl to public) is needed, the Impl class must be
   derived from boost::noncopyable
5) All public classes have non-default copy constructors that make a copy of the
   Impl class
