    @brief Definition of the IdentifierDistributor class

    The IdentifierDistributor makes sure that only one instance of ClassIdentifier for each
    template parameter T exists. All Identifiers are stored in a map with their name.
    IdentifierDistributor is a singleton class, it can't be created or deleted directly.
