Removed the alpha Euler angle from the isotropic code frame order model.

Removed unused code from MF_result_command.run().

The minimisation stats don't need to be placed into the memo!

Added more comments to run_command_queue().

Comment simplifications.

Removed the unnecessary IO buffer flush added in the last commit.

Cleaned up the run_command_queue() method idle and running set print outs.

The code has also been commented.

Bug fix for the model-free optimisation.

The data containers used to store all the model-free info and optimisation parameters was being
overwritten so each command sent to the processor queue contained only the data of the last spin
system.

Argument rearrangement.

Added comments and docstrings to the MF_memo and MF_result_command classes.

Important bug fix for the R_to_euler() function.

The special angle wrapping when beta was negative is only for the ijk Euler notation when i == k!
When i != k, another type of wrapping will be required.
