// Service definiton

module.exports = function(){
  const app = this;
  const db = new NeDB(...);
  // ...
  app.use('/projects/:projectId/sync', projectsSyncService);
  
  const docs = { description: 'My Project Service' }
  app.use('/projects', Object.assign(service(options), { docs }) );

The first app.use spawns the projects tag in the spec and the docs definition from app.use('/projects' gets ignored by
https://github.com/feathersjs/feathers-swagger/blob/master/src/index.js#L220

The workaround is add the docs to the very first use but it's way confusing and the sub-service should hold its own docs. Probably we should use the group-defs only for first-level paths or merge the defs?
