GUI Review Page

The GUI review page is currently not implemented. The purpose of this page is to check submission status (whether datasets have been approved by community administrators yet), and communicate with the admin in a similar way to that found on the AE Datastore web interface. Review page should also support a method of editing submissions. This ensures users would not need to leave the NekUpload interface to perform all actions related to dataset editing and review, and ensures consistency in dataset uploads.
