Koa-ACL-Swagger

NOTICE: can not be used in production

a role base access controller and working with swagger (named OpenAPI now)

In YAML file, add x-resource option to each path. when a user visit this url, the middleware will check the permission based on resource name and HTTP method. like "user test-user have the permission post of the resource pets". so you should set role-base permission before.

see demo in examples/app
