C.Wu: trying to add interface to change default xyz position for primary generator; deleted chargedgentino from the black list of steplimiter; reverting cdc geo&sd back to old version
C.Wu: CDC parameter rule fixed! hopefully!
C.Wu: now we can set default position in macro!
C.Wu: now we can set pid mode and default particle name
if we find sum_fac not 1 we'd better out put the current value
C.Wu: added interface to set the offset of fieldmap; x,y,z are the coordinates of new origin in old coordinate
C.Wu: forgot to add PHYSICSLIST in Example/setenv.sh!
