Public API Changes

Require At Least One AppointmentType for /AppointmentTypesSync

Overview: API Maintenance

Previously the /AppointmentTypesSync would return successfully even if no appointmentTypes are included, which was confusing. If no appointmentTypesare included, the /AppointmentTypesSync API now returns an error to say that at least one appointment type is required.  Additionally, specific errors will be supplied if the ID or summary is not populated, as both are required or are too long.
