Added the fPatternSize variable to the copy constructor for QwHelicityPattern. There is still the possible frailty since it relies on "bcm_an_us" being a good variable to monitor good events. Considering a parameter to run range the name of the good current monitor (as far as i recall, this was changing over the course of PREX). That will be a robust fix. But this should work for now.
