Functional Description:
The Sync and Freeze pair of operators is used to allow the master to get outputs and set inputs consistently.  Its primary use as would be to synchronize multiple slaves, change the data on each one, then issue an 'unsync' so all the outputs on all the slaves change at the same time.  Slaves need to be grouped into sync/freeze groups to accomplish this. Sync locks output data on slaves until the master issues an 'unsync'. Freeze locks input data on all slaves until the master issues an unfreeze'.

User-Defined Properties:
Name. A string label that identifies the operator

Broadcast Group. All - every slave or select one of eight slave groups for the operation.

Comments: None.
