cb672c7992 overflow example works 
- introduce weak/strong eval to temper unit propagation to use only weak evaluation.
- harness the amount of interval propagation provided on overflow constraints
- weak evaluation on overflow constraints is now trivialized
- viable insertion also does conflict detection
