Add a script to execute runSofa on a series of scenes
Add a script to execute runSofa on a series of scenes

Usage example:

$ cd path/to/src/
$ cp -r examples path/to/build/
$ ./scripts/test-scenes.sh path/to/build examples

This would execute runSofa in batch mode on each on the examples, and
save its exit status and output respectively in:
- path/to/build/test-scenes-status.log
- path/to/build/test-scenes-output.log
