    @brief
        The PickupCollectionIdentifier is the specialization of the PickupIdentifier for the @ref orxonox::PickupCollection "PickupCollection" class.
        It identifies @ref orxonox::PickupCollection "PickupCollections" based on the different @ref orxonox::CollectiblePickup "CollectiblePickups" they consist of.

        @ref orxonox::Pickupable "Pickupables" (resp. @ref orxonox::CollectiblePickup "CollectiblePickups") can be added to the PickupCollectionIdentifier via the addPickup method.
