Fix for a link to http://www.nmr-relax.com/manual/minimise_calculate.html.
* Completed the Relax_fit.test_zooming_grid_search system test. Now only a single spin is optimised. The zooming levels increase in integer increments from 0 to 50 so that the final zoomed grid is insanely small (as the curve-fitting C modules are incredibly fast, this test is nevertheless relatively quick). The final zooming grid search parameter values are checked to see if they are the same as those optimised in the Relax_fit.test_curve_fitting_height system test to demonstrate the success of the algorithm.
* Modified the grid search upper bounds functions for the relaxation curve-fitting. This is for both the exponential relaxation curve-fitting analysis and the same fitting in the dispersion analysis. The intensity values are doubled and then rounded to the next order. This ensures that I<sub>0</sub> and I<sub>∞</sub> will be within the grid bounds. Hence the zooming grid search can be used for these curves.
* Expanded the [documentation for the http://www.nmr-relax.com/manual/minimise_calculate.html documentation for the minimise.calculate user function]. This now explains the dual operations of the user function.
* Fixes for some relaxation dispersion system tests not converted to the new optimisation user functions. Minimisation is now via the [http://www.nmr-relax.com/manual/minimise_execute.html minimise.execute user function], which used to be the [http://www.nmr-relax.com/manual/minimise.html minimise user function].
* Added a 128x128 pixel version of the zoom-in Oxygen icon. This icon size is not available in the repository located at svn://anonsvn.kde.org/home/kde/trunk/kdesupport/oxygen-icons. Therefore the scalable/actions/small/48x48/zoom-in.svgz file was copied and then exported into a 128x128 PNG, and finally converted to a Gzipped EPS file for the relax manual.
