    \brief Definition of the proto class template, used quickly start work
    \todo Example: this shows how to use simply add a Marker that here has to be done something.

    The Protoclass exists, to help you quikly getting the run for how to develop in orxonox.
    It is an example for the CODING-CONVENTION, and a starting-point for every class.
