- added documentation about how to implement an exporter

- added a Python data exporter example (can export rigid bodies in all formats supported by meshio)
- added an OBJ rigid body exporter
- implemented a simple interface to register own particle and rigid body exporters
- extracted the scene configuration in a singleton class
- simplified the interface to register a new non-pressure force
