v0.2.0

Changed

The public API is changed in a way that the OpenAPI spec generation is split out from the input/output validation. The validation is now done with input and output keywords within the defineEndpoints handler, that generates a minimal OpenAPI spec out of the contents of the input and output definitions and all other OpenAPI generation-related overrides are done inside the openApiSpec object. This makes the separation of the business logic and documentation clearer, while still auto-generating the definitions from the application logic.
