Jobs with few PS crash the scenarioTwinViewer1 scenario

[Fabulani]

In the OP states of the scenarioTwinViewer1.py scenario, a constant is used to define which PS to begin. This causes a list out of index type of error when the Job that is being executed does not have the standard amount of PS.

A work-around would be avoiding the creation of Jobs without the default amount of PS.

A possible fix would be implementing state transitions according to the to-be-executed PS. The order of execution could be defined by the PS list itself, or by a tree-structure if parallel execution is desired. This can also lead to very confusing diagrams, as shown below.
