The NUM_INT_PTS variable in the system tests scripts is now passed into the frame_order.sobol_setup
user function as the max_num argument. This number has also been changed so that the tests take a
reasonable amount of time. All chi2 value checks were updated. These were validated by increasing
the number of integration points and watching the chi2 value of the Frame_order.test_cam_*_pcs
version of the system tests head to zero.
