FPGATrackSim: Implementing new linear tracking technique by passing only the lowest chi2 track per each road

Hello,

I have edited the source code for first and second stage track passing in order to only pass the lowest chi2 track per road within FPGATrackSim. This does not significantly impact the efficiency of either stage, while also removing duplicates, specifically when running over ttbar pileup. I presented on the topic in a US ATLAS EFTracking meeting and followed through on all additional tests that were recommended. They all had the same results as listed above.

The changes in the source code are implemented here: Trigger/EFTracking/FPGATrackSim/FPGATrackSimAlgorithms/src/FPGATrackSimLogicalHitsProcessAlg.cxx Trigger/EFTracking/FPGATrackSim/FPGATrackSimAlgorithms/src/FPGATrackSimSecondStageAlg.cxx

There is also a working flag implemented for the tool which is built into the config files.

Best regards, Osip
