New Revision: 25335

URL: http://svn.gna.org/viewcvs/relax?rev=25335&view=rev
Log:
Changed the relax_fit.py sample script to use Newton rather than Simplex 
optimisation.

This can lead to significantly faster optimisation times, as shown in the 
commit message
http://article.gmane.org/gmane.science.nmr.relax.scm/23081.
