Description

This function finds the type library associated with the ProgID and tries to find the type information of an interface called ``interface_name''. If it does, then creates an object whose implementation is ``impl_table'', that is, any method call or property access on this object is translated to calls or access on the members of the table. Then it makes a LuaCOM object for the implemented interface and returns it. If there are any problems in the process (ProgID not found, interface not found, interface isn't a dispinterface), the function returns nil.
