    Change of default Units.
    It has long been on the list of things to do to change the BrUnits
    default from MeV to GeV. This is done now. The places in the code
    where this is of importance is in
    
    BrGeantHit.cxx
    -- conversion from .cdat information to dedx is (already) controlled
    by the BrUnits::KeV constant.
    BrDigitizeTPC.cxx
    -- conversion from .cdat information to dedx is (already) controlled
    by the BrUnits::KeV constant.
    BrDigitizeTof.cxx
    -- added the BrUnits::MeV to the conversion from dedx to adc (4 places 
    in code).
    BrModuleMatchTrack.cxx
    -- added back the BrUnits::GeV in conversion from bend angle to
    momentum.
    
    The idea of using BrUnits for all formula is that if a units is
    changed (e.g. a default) results will all show up in the appropriate
    unit.
    
    The other defaults are cm and nsec as before.
    
    Please report problems with this, in particular if there are other
    pieces of code that assumes certain MeV or GeV units.
