ClassNotInstantiatedInspection

A class module is never instantiated: Rubberduck should hint about it, and a quickfix should be in place to remove the class from the project (uh, and prompt for user confirmation before doing so!).

Note the emphasis on hint - VBA classes can have a default instance, so a class that is never instantiated isn't necessarily a class that is never used.

We've talk before about whether or not it makes sense to export the files before parsing in order to get to the attributes. This is a great case for doing that. It would allow us to pick up the PredeclaredId attribute. If it's true, the class has a default instance. Which means it is declared and this inspection shouldn't pick it up. Of course, that would probably mean regenerating the parser from a new grammar.

The .g4 grammar we're using already handles module-header attributes - no grammar change is needed for this!
