point_metrics compiling issues

[zhiyaol]

1: In line 2, import qp It seems like qp is never used anywhere else in the file
2: In line 80 for calculatingOutlierRate function, print "using %.3g for cut for whole sample and %.3g for magcut sample\n"%(cutcriterion_all,cutcriterion_magcut) doesn't compile and could be updated to include parentheses like print ("using %.3g for cut for whole sample and %.3g for magcut sample\n" %(cutcriterion_all,cutcriterion_magcut))

All of the PhotoZDC1 analysis used python2.7, as qp was not python3 compatible (working on updating that now), so I wouldn't be surprised if there were other python2 features that do not work in python3 still in the code.
