* traces - added some routes, replicated data access / pagination, but presentation and pending file control not complete * edit - setup so that applet can be loaded + token authorisation enabled * API - tests out ok against applet, but had to change segment-node associations * misc - gems version required upgraded to 1.2.3 (latest stable rails version), changed some find_first to find(:first... calls
