// AuthorizerFactory is used by the RTI to construct instances of classes
// derived from Authorizer.
// An authorizer library includes one or more subclasses of Authorizer,
// one or more subclasses of AuthorizerFactory (which is used to create
// instances of those Authorizer subclasses), and a single implementation
// of AuthorizerFactoryFactory::makeAuthorizerFactory.
// This static function should choose a AuthorizerFactory based on the string
// identifier passed as an argument, and return an instance of that kind of
// factory.  The RTI will call this function to obtain an AuthorizerFactory,
// and then will use that factory to create any instances of Authorizer that
// it needs.

// All RTIs shall implement a reference authorizer library with an authorizer
// named HLAauthorizer. The interfaces for these types shall
// be found in the auth subdirectory.
