Revision: 9609
Author: rchan...@google.com
Date: Tue Jan 25 08:05:30 2011
Log: Updates DTRF to show the use of ServiceLocators and Locators.
- Added editors to modify person schedules
- Schedule is now a RF Entity and TimeSlot is now a VO
- ScheduleLocator interfaces with "non standard" getKey and getRevision
methods
- ScheduleService provides a service method
