relaxGUI creates a dummy file for unresolved spins that will be used in relax_fit.py

The relaxGUI controller updates its progress bar using informations from the status singleton during model-free analysis.

Currently, there is a maximum of iterations set for models 1 - 5. This also has to be set in the dauvergne_protocol.py script. Edward, what do you think about limiting to 20 iterations?

Status for local tm models is correctly assigned in dauvergne_protocol.py.

The ellipsoidal diff tensor check in check_ellipsoid() now functions better.

The diffusion elements are scaled down to the order of 1 so that the assertAlmostEqual() calls do
not fail with tiny machine precision differences.

The ellipsoidal diff tensor relaxation data was not fully regenerated in r11056.

The spheroid diffusion tensor optimisation test now checks the values.

The simulation of PDB coordinate truncation now occurs after vector scaling by r.

This should now be a more accurate representation and allow relax to find these values exactly.

The unit bond vectors are now normalised using the numpy.linalg.norm() function.

Fixes for the tests of the spheroid diffusion tensor.

Modified the spheroid diffusion tensor data generation so that Z is the symmetry axis.

This will allow direct mapping of Euler angles to spherical angles!
