Detailed Description

Sequencer for executing several algorithms, stopping when one is faulty.

Default behaviour (ModeOR=False) is to execute all algorithms until one returns filterPassed() = False. If ShortCircuit is set to False, then all algorithms will be executed.

In OR mode, the logic is opposite. All algorithms until one returns filterPassed() = True. To then exit one must conter-intuitively set ShortCircuit to False. If the default value ShortCircuit=True is left then all algorithms will be executed.
