/** the UNO3_GETIMPLEMENTATION_* macros implement a static helper function
that gives access to your implementation for a given interface reference,
if possible.
Example:
MyClass* pClass = MyClass::getImplementation( xRef );
Usage:
Put a UNO3_GETIMPLEMENTATION_DECL( classname ) inside your class
definitian and UNO3_GETIMPLEMENTATION_IMPL( classname ) inside
your cxx file. Your class must inherit ::com::sun::star::uno::XUnoTunnel
and export it with queryInterface. Implementation of XUnoTunnel is
done by this macro.
