Created a script for byte compiling the Python source files.

Fix for the model-free _determine_model_type() method when the spin container has no 'local_tm'.

This code was failing in certain rare circumstances (when the setting up of the diffusion tensor was
forgotten).

Removed some debugging print out statements.

Fix for the model-free model choice buttons - they now size properly and are not too wide.

Fix for the pipe creation with a new model-free auto-analysis tab.

The pipe type was being set to 'noe'!

Spacing improvements in all the auto-analysis GUI elements.

The add_border() coloured debugging is now specified by an argument.

Better spacing in the steady-state NOE auto-analysis GUI element.

Better spacing in the Rx auto-analysis GUI elements.

add_border() with debugging now creates coloured borders.
