Deleted the printout in dep_check. The printouts are only used for the essential packages before calling sys.exit()

Task #7807 (https://gna.org/task/index.php?7807): Speed-up of dispersion models for Clustered analysis.

Updated the chi-squared values being checked for the double rotor frame order system tests.

The double rotor frame order system tests are no longer blacklisted.

Fix for the double rotor frame order matrix assembly function.

The rotations where applied in reverse, hence the 2nd degree frame order matrix was the Kronecker
product transpose of the correct form.

Fix for the Frame_order.test_cam_double_rotor_large_angle* system tests.

The system test script was pointing to the wrong data directory.

The second torsion angle is now printed out for the frame order system tests.

This is in the system test class mesg_opt_debug() method and allows for better debugging of the
double rotor models.

Attempt at implementing the 2nd degree frame order matrix for the double rotor model.

This is required for the RDC.

Added proper support for the double rotor frame order models to the system test scripts.

This is for the CaM synthetic data. The base script can now handle the current parameterisation of
the double rotor model with a single pivot, an eigenframe, and the second pivot defined by a
displacement along the z-axis. The scripts for the double_rotor and double_rotor_large_angle data
sets have been changed to use this parameterisation as well.

Small fix for the large angle CaM double rotor frame order model synthetic test data.

The way the rotation angle was calculated was slightly out due to integer truncation. The integers
are now converted to floats in the generate_distribution.py script and all of the PCS and RDC data
averaged over ~20 million states has been recalculated.

Added matrix_power to the init file in lib/dispersion.
