I added the /me route for obtaining user profile from access token.
I updated documentation and changelog.
I enabled cors for /me route.
I added new notifications after create / update / delete operations which are received by resource validator classes.
I improved json serializer so that it automatically formats datetime fields.
I correctly implemented one level nesting queries in roa and model filter. Only unit tests pass so far.
I fixed the integration tests for nested filtering in simple and coumpound operators.
