TriggerAlg::tracker and TriRowBitsAlg
The code to compute the 3inARow condition based on digi is duplicated between these 2 pieces of code. This is even dangerous, as everything in TriggerAlg relies on the local computation which ends up in EventHeader, while it is the version in TriRowBitsAlg that actually makes it to the TDS and then to the L1 ROOT object.
What should be done :
1) reverse TriggerAlg and TriRowBitsAlg in the basicOptions.txt
2) remove the code in TriggerAlg::tracker and replace by a call to the TDS.
