Feature or enhancement

Proposal:

Proposal:

• AddBRANCH_TAKEN andBRANCH_NOT_TAKEN events tosys.monitoring
• Deprecate the oldBRANCH event (as it will be redundant)
• MonitoringBRANCH events implicitly monitors both theBRANCH_TAKEN andBRANCH_NOT_TAKEN events
• Disabling aBRANCH_TAKEN event will implicitly disable the matchingBRANCH event, but only for the taken branch
• Disabling aBRANCH_NOT_TAKEN event will implicitly disable the matchingBRANCH event, but only for the not-taken branch
• Disabling aBRANCH event will implicitly disable the both the matchingBRANCH_TAKEN andBRANCH_NOT_TAKEN events

This is fully backwards compatible.
