    @brief
        Is a Singleton and manages @ref orxonox::Quest "Quests", by registering every @ref orxonox::Quest "Quest" / @ref orxonox::QuestHint "QuestHint" (through registerX()) and making them globally accessible (through findX()).
        @ref orxonox::Quest "Quests" (and @ref orxonox::QuestHint "QuestHints") are registered in the QuestManager with their id, and can be accessed in the same way.
