[Michael Mirwaldt]

> This s my initial draft fo a sample testing solutions for the dining philosophers problem:
> - Wikipedia explains it on https://en.wikipedia.org/wiki/Dining_philosophers_problem
> - It runs within 13min on my machine.
> - It includes a short comment about the motivation for that sample and
> a reference link to the wikipedia article about the dining philosophers problem. 
> - It offers 3 different solutions: with monitors, with reentrant locks and with semaphores
