#977 CIF controller checker: warn if model has no input variables. (!1051) · Merge requests · Eclipse Projects / Eclipse ESCET (Supervisory Control Engineering Toolkit) / escet

Best to review per commit.
CIF controller properties checker now warns if the input specification has no input variables. This points to missing a hardware mapping.
I also copied CifCollectUtils.collectInputVariables from !1050 (merged).
I did not update the documentation. I've created #978, where that can be done.
