Combination of triggers

[fjullien]

In the current implementation, adding triggers adds trigger to a sequence.
It would be great to combine triggers not only in sequence but in a AND or OR logical group.
Could be a global configuration:

analyzer.configure_mode(SEQUENCE/OR/AND)

• In SEQUENCE mode, we would have the current behavior,
• In AND mode, all trigger conditions must occurs at the same time,
• In OR mode, one the the trigger conditions must occur.
