Usage

1: develop a class in ABAP with public methods

2: implement interface ZIF_SWAG_HANDLER, and register the public methods(example method zif_swag_handler~meta)

3: the methods are now accessible via rest(example)

4: the Swagger UI can be accessed via swagger.html in the base dir of the REST services
