class AliITSTriggerFOProcessor

Author: Henrik Tydesjo

This class takes care of simulating the output from the pixel
trigger system.
The fast-or signals are given as input and they are processed
to see which algorithm will give a signal to the central
trigger system. To avoid doing the same operations many times,
there is a method called PreprocessFOSignals, which should
always be called for each event before the processing of
each individual algorithm is done.

As soon as a new algorithm has been implemented online, a
corresponding method should be implemented here. Which method
should be used for a given trigger label is taken care of in
ProcessFOSignalsLabel method.
