Interactive generation of qadapter in run_session and run_model using CLI and GUI interfaces

The features from MRs vre-middleware!86 (merged) and vre-middleware!87 (merged) of the VRE Middleware could be adapted to the VRE-Language to enable interactive, and simple, generation of a qadapter for both run_session.py and run_model.py scripts. Ideally, CLI and GUI interfaces should be provided to facilitate the use of such interactive qadapter building tool.
