Clean up of the metal_pos_opt.py system test script.

Fixes for the N-state model optimisation set up if PCS or RDC data is not loaded.

Revert the reversion of revision r14853 which was a reversion of r14849, as it was ok!

The command used was:
svn merge -r14853:r14852 .

.....
Reverted r14849 as this was not the correct solution to the problem!

The command used was:
svn merge -r14849:r14848 .

r14849 | bugman | 2011-10-12 17:40:47 +0200 (Wed, 12 Oct 2011) | 5 lines
Changed paths:
M /1.3/maths_fns/n_state_model.py

Yet another fix for the N-state model target functions.

The Ln3+ optimisation with the tensors fixed was resulting in a chi2 value of 0 at all times!
.....
.....

More fixes and improvements to the test_metal_pos_opt() system test.

Reverted the last revision (r14860) as the change was rubbish.

The command used was:
svn merge -r14860:r14859 .

Fix for the position checking in the metal_pos_opt.py script.

More attempts at fixing the N-state model code.......

Added a check that the chi2 value is no longer zero if the Ln3+ is moved in the metal_pos_opt.py test.

Added another chi2 of zero check to the metal_pos_opt.py system test script.

The chi2 of zero test in the metal_pos_opt.py system test script is now not exact.
