Modified the execution lock to have a mode.

This allows for greater control and avoid string comparison of names to determine if a script or
auto-analysis acquired the lock.

The dauvergne_protocol system test script can now run stand-alone.

Re-activated and redesigned the system test of the dauvergne_protocol.

Fix for the dauvergne_protocol sample script - the mc_num arg is now called mc_sim_num.

The PDB file and unit vector loading are now performed in the model-free auto-analysis GUI test.

The main gauge in the relax controller is now pulsed with a wx.CallAfter() call to avoid race conditions.

The unit vector loading wizard is now stored in the base model-free auto-analysis class.

This is for access to the GUI element from the test-suite.

Fix for the unit vector check in the model-free auto-analysis tab.

Added a button and created a wizard for loading unit vectors from PDB files.

This has been added to the model-free GUI auto-analysis tab.

Unit vectors are now only checked for in the model-free GUI auto-analysis when needed.
