The create_molecule, create_residue, and create_spin functions now returned the created container.

This should not affect any of the current code using these, as normally None would be returned.

Created transparent background images of the diffusion tensors for the model-free auto-analysis tab.

Deleting the function 'vector_xyz' in the generic_fns/structure/main.py

The code of the function 'vector_xyz' was removed since it will be not used.

Added a series of 4 buttons for calling value.set in the model-free auto-analysis tab.

This is to make it obvious that the CSA, bond length, heteronucleus type, and proton type need to be
set.

A number of improvements to the value.set GUI user function.

The on_display() method has been renamed to update_parameters() so the parameter list can be
updated only when needed. The set_param() method has been added to set a starting parameter and its
default value.

The GUI user functions now show a busy cursor when loading.
