Seperate analysis of entry points

[TamaraGunkel]

Currently, our analysis searches for entry points in the process. Two possible entry points are e.g.

ProcessInstantiationBuilder instantiationBuilder = processEngine.getRuntimeService()
              .createProcessInstanceByKey("myProcess")
              .setVariable("var", "value");
instantiationBuilder.execute();

this.runtimeService.startProcessInstanceByKey("myProcess", processVariables);

The variables which are passed to the process are included in the analysis. However, it is possible that a process is started twice within a project. In this case, the variables are currently merged (union of variable sets).
The correct way would be to run two seperate analyses, one per entry point.

To implement this extension, the analysis must be conducted per entry point and the frontend must be changed accordingly.
