Use operation summary and description in generated function docs (#67)
### Motivation For generated functions for each operations we generate reference documentation. Currently this only states the HTTP information and the operation ID, and doesn't include either the `summary` or the `description` that may be present in the OpenAPI document. ### Modifications Change the reference documentation to include both the summary and the description if they are provided. ### Result Reference documentation for operation functions contains the documentation from the OpenAPI document. ### Test Plan The OpenAPI document used in the reference test includes operations with and without these fields. ### Resolves - Resolves #64. --------- Signed-off-by: Si Beaumont <[email protected]>
