As a developer I want to see which process variables are defined but never used

[TamaraGunkel]

It would be helpful to identify process variables which are set/defined during the process but never used (-> clean code). This could be archieved by using the "out-unsed" sets of end events. These sets should include all variables that weren't used yet. This approach should be vaild for normal processes and subprocesses.

I approve that as discussed earlier 👍
