/** Action Registry.
 *
 * The Action registry is a storage for any Action instance to retrieved by name.
 * It is a singleton and can be called from anywhere.
 *
 * ActionRegistry::fillRegistry() is the essential function, called in the cstor,
 * where all the prototypical Action's are instantiated. To this end, we sadly
 * require a global list of all present actions (\note there is a regression test
 * check on its completeness). We include \ref GlobalListOfActionsh.hpp where a
 * boost::preprocessor sequence is contained that is then used to install each
 * of the Action's in the registry.
