It has to walk through all examples contained in python/simulation directory to automatically produce *.png images.
The script will serve to two purposes.
1. During the release we can run the script to make sure that examples are not broken.
2. The *.png images produced by the script we can use to upload on our web site to reduce the amount of manual work.
> In principle, we can even ask the script to compare produced images with whose stored on website. And in the case of difference, the script will notify us that the examples section of the website needs to be updated.
