    keyword=ADC Helicity Added to Replay Files

    I have added the helicity signals from the ADCs to the replay.C and the
    output definition files for the left and right HRS, though the channel
    map for the R-HRS is not correct. If needed, it should be easy to find
    the channels and add them.

    There are two copies of the helicity from the ADC. The variables have
    the prefix adchel.L.* and adchel2.L.*. Since adchel.L.helicity and
    adchel2.L.helicity are copies, they should be equal. I have added the
    following flag into the replay_det.cdef file on the bbsoftw account:

    bad_adchel adchel.L.helicity!=adchel2.L.helicity

    in the Block: Decode section. At the end of the replay, the number of
    events that passed this cut will be displayed. It should always be 0!

    As far as the helicity from the TIR (G0 helicity), there are still a few
    issues in the decoding. I hope to have the code working later today.
