    /**
    @brief
        The a WeaponSlot defines where a @ref orxonox::Weapon "Weapon" is placed on a pawn. A WeaponSlot is a @ref orxonox::StaticEntity, therefore it has a position and orientation.
        In a WeaponSlot there can be only one "Weapon", but a Weapon can have several @ref orxonox::WeaponMode "WeaponModes".
        A WeaponMode is what one intuitively imagines as weapon. (E.g. RocketFire, LightningGun, LaserFire are weaponmodes)

        A WeaponSlot is created in XML (in a weaponsettings file), which can be done in the following fashion:
        @code
        <weaponslots>
          <WeaponSlot position="-15.0,-1.5,0" />
          <WeaponSlot position=" 15.0,-1.5,0" />
          <WeaponSlot position="    0,   0,0" />
        </weaponslots>

        A WeaponSlot can be attached to a @ref orxonox::Pawn because WeaponSlot inherits from @ref orxonox::StaticEntity.
