Updated the minimum minfx dependency version number from 1.0.9 to 1.0.11 in the dep_check module.

This newest version handles infinite target function values preventing optimisation from continuing
forever (https://gna.org/forum/forum.php?forum_id=2477). The 1.0.10 version is also useful as there
is full support for gradients and Hessians in the log-barrier constraint algorithm
(https://gna.org/forum/forum.php?forum_id=2475).

Implemented the pseudo-Brownian frame order dynamics simulation for the single motion models.

This uses the same logic as in the test_suite/shared_data/frame_order/cam/*/generate_distribution.py
scripts which were used to generate all of the test suite data. However rather than using a random
rotation matrix, a random 3D vector is used to rotate a fixed angle. And the rotation is used to
rotate the current state to state i+1. The rotation for the state is decomposed into torsion-tilt
angles once shifted into the motional eigenframe, the violations checked for as the state shifted to
the boundary, then the new state reconstructed from the corrected torsion-tilt angles, and then it
is shifted from the motional eigenframe to the PDB frame.

Fix for the new specific_analyses.frame_order.geometric.generate_axis_system() function.

The rotor and free rotor models were not correctly handled and the returned eigenframe was the zero
matrix.

Created a basic text based progress meter in the new lib.text.progress module.

This is taken from the script test_suite/shared_data/frame_order/cam/generate_base.py.

Modifications to the User_functions.test_structure_add_atom GUI test.

As lists of lists are now accepted by the structure.add_atom user function, the operation in the GUI
is now significantly different. Therefore many checks have been removed from the GUI test.

Added safety checks for NaN values to the lib.structure.pdb_write module.

This is within the _record_validate() function. The check prevents the creation of invalid PDB
files.

Created the specific_analyses.frame_order.geometric.generate_axis_system() function.

This is now used by most parts of the frame order analysis to generate the full 3D eigenframe of the
motions. Previously this was implemented each time the frame or major axis was required. This
replicated and highly inconsistent code has been eliminated.

Changed the default PDB file name for the frame_order.simulate user function to 'simulate.pdb'.

The '*.bz2' extension has been dropped so that the file is quicker to create and does not need to be
decompressed for loading into molecular viewers.

Improvements for the frame_order.simulate user function.

The rigid model is now skipped, the PDB file closed, and some printouts for better user feedback
have been added.

Implemented the shifting to the average position for the frame_order.simulate user function backend.

This simply sends the structural object into the new average_position() function of the
specific_analyses.frame_order.geometric module.
