Created a truncated OMP PDB file with only NH vectors of the first 15 residues.

The molmol residue name syntax has also been fixed to allow Modelfree4 to be happy.

Fix for the test_palmer_omp() system test.

The PDB file has no models in it!

Bug fix for the create() method. Deselected spins should be skipped.

Created a system test for Modelfree4 with the OMP data.

This runs the palmer_omp.py system test script.

Removed the reading of the PDB file and setting of a spheroid tensor.

This will be tested in a second system test.

Created a new script to test out the handling of Modelfree4 with PDB files and spheroid diffusion.

Fix for the execute() method when a PDB file is being used.

Modified the Modelfree4 system test to use a PDB file and spheroid diffusion tensor.

More fixes for create_run().

Fix for running Modelfree4 - the structure is properly copied in the create_run() method.
