The frame_order.pivot user function can now be used to turn the pivot optimisation on and off.

If the pivot point is not given, this user function will now just set the fixed flag and nothing
else, allowing the optimisation status of a pre-set pivot to be changed.

Updated the Python download links for version 2.7.6 at http://www.nmr-relax.com/download.html.

Added a sentence to the wxPython section explaining why Python 2 is necessary.

This is for the download page http://www.nmr-relax.com/download.html.

Simplified all of the CaM frame order optimisation testing scripts.

These are for the synthetic test suite data. The unnecessary class structure of the scripts has
been eliminated.

Updated the ancient test_suite/shared_data/frame_order/cam/rotor2/pcs_only/frame_order.py script.

This now matches the script of its parent directory.

Updated all of the frame order optimisation scripts for the CaM test suite data.

These simple testing scripts were very much out of date and non-function for the current code. Half
of the code in these scripts is now implemented in the concise frame_order.pdb_model user function.

Renamed the specific_analyses.relax_disp.disp_data module to specific_analyses.relax_disp.data.

This is to match the module naming convention used in the other specific analyses, and as detailed
in the post http://thread.gmane.org/gmane.science.nmr.relax.devel/5294.

Merged the Van't Hoff and Arrhenius lines of the dispersion software comparison table of the manual.

These are the same analysis.

Correction for the nu_CPMG to tau_CPMG conversion formula in the dispersion chapter of the manual.

In relax, the conversion nu_CPMG = 0.25 * tau_CPMG is used and not nu_CPMG = 0.5 * tau_CPMG.

Indentation fixes for the test_suite/shared_data/frame_order/cam/generate_base.py script.

This was broken during the merger of the double_rotor branch.
