This reflects the current state originally implemented by Endrju and Sobhi.
Add general concepts which may be used in all of the existing model types

This reflects the current state originally implemented by Endrju and Sobhi.

This reflects the current state originally implemented by Endrju and Sobhi.
Add cardinalities for concepts of model type 'composition/decomposition'

This reflects the current state originally implemented by Endrju and Sobhi.
Merge branch 'feature-cardinalities' into develop

Implement first AdoScript to check whether a given model meets certain constraints

This analyzes the current model and stores all the possible paths from an outgoing 'StartEvent'.
Further details are given below:

1. The model to be analyzed has to be of type ControlFlow_20130808. If it is not further execution is being canceled.
2. All existing concepts/classes of type StartEvent are being listed; the number of StartEvents being 1 is a condition for further proceedings.
3. All the possible paths beginning with a StartEvent are stored in an multi-dimensional array.
4. Echos whether a certain path ends in an Event called StopEvent or not.
Merge branch 'feature-150' into develop

First implementation of an algorithm for checking constraints.
