/// This method is used to register a type with the Astoria runtime which may be returned in the �open properties� of
/// an open type such that the type is visible in $metadata output and usable with CRUD operations.
///
/// The typename parameter must be a namespace qualified type name (format: <namespace>.<typename>).
/// The name provided must be as it would show up in a CSDL document (ie. model types, not CLR types)
///
/// The types registered via calls to EnableAccess will be additive to those implicitly made accessible via
/// DSC.SetEntitySetAccessRule(�) invocations
/// � Note: The Astoria runtime layer won�t be able to determine if a typename specified maps to an Entity Type,
/// Complex Type, etc until it actually obtains type info (entity types, complex types, etc) from the underlying provider
/// � �*� can be used as the value of �typename�, which will be interpreted as matching all types
///
/// When Astoria enumerates types or needs to obtain a type (Complex Types, Entity Types) from the underlying provider
/// it will first determine if the type should be visible (show in $metadata and accessible via operations exposed by the
/// service) as per the standard v1 checks (ie. driven by SetEntitySetAccessRule calls). If the type is not visible via V1
/// rules, then we consult the set of types registered via EnableAccess(<typename>) invocations. If the type was
/// included in such a call then the type is visible via $metadata and can be accessed via CRUD ops, etc.
///
/// If a type is not made visible via one of the mechanisms above, then:
/// � That type must not be included a response to a $metadata request
/// � Instances of the type must not be returned to the client as the response of a request to the data service.
/// If such a type instance would be required the service MUST fail the request. Failure semantics are covered
/// in the area of the specification which covers request/response semantics with respect to open types.
///
/// Invoking this method multiple times with the same type name is allowed and considered a �NO OP�.
