Task #7826 (https://gna.org/task/index.php?7826): Write an python class for the repeated analysis of dispersion data.

Adding another statistic method to plot for multi-data sets.

Task #7826 (https://gna.org/task/index.php?7826): Write an python class for the repeated analysis of dispersion data.

Shifted the checks for the Dasha and Modelfree4 software into the system test __init__() method.

This is to bring this into the same design as the relaxation dispersion tests which require the
NMRPipe showApod software. Now the test suite will list either Dasha or Modelfree4 in the skipped
test table if they are not installed.

Extended the printout for the skipped tests in the test suite.

As tests using the NMRPipe showApod software are skipped and listed in this table, the text now
includes 'software' in the list.

Added the Relax_disp.test_show_apod_rmsd_dir_to_files system test to the blacklist.

This is if the showApod program is not installed on the machine and allows the test suite to pass.

Fix for the frame order count_sobol_points() function.

The torsion angle ranges from -pi to pi, so the absolute value needs to be checked, just as in the
lib.frame_order modules.

Created the Frame_order.test_count_sobol_points_iso_cone_free_rotor system test.

This is to test the frame_order.count_sobol_points user function for the free-rotor isotropic cone
model.
