hi blasters!
  this is a repeat of my earlier message with the subject fixed and an
update:

> i added a new track fitter `WCnewt' to the class TBLRecon. it has the
> advantage of essentially converging in one iteration. to see it in
> action, set printFlag=1 in s.C and run it. it outputs the chi^2 for
> each type of fit, and the number of iterations (minuit isn't working
> right now). to see how well WCnewt does on each iteration, you can set
> printFlag=1 or 2 (for more info) int TBLRecon.cc::WCnewt

  now also, the minuit track fitter is fixed. you can see a comparison
of the different fitters in the cvs logfile of `s.C'.
