Fix for the relax_fit.select_model user function backend for the 'sat' model.

Modified the Relax_fit.test_saturation_recovery system test script.

The relax_fit.select_model user function call now selects the 'sat' model.

Added the saturation recovery experiment to the relax_fit.select_model user function.

This simply adds a new option and sets up a different parameter set [Rx, Iinf].

Created the Relax_fit.test_saturation_recovery system test.

Modified the relax_fit_saturation_recovery.py script to work as a system test.

The status.install_path variable is now used to point to the location of the files. The relax data

been deleted.

Added a system test script for testing the saturation-recovery R1 experiment.

This was created by Andras Boeszoermenyi <Andras_Boeszoermenyi att hms dott harvard dot edu>. The
file was taken from the saturation_recovery.tar.gaz file
(https://gna.org/task/download.php?file_id=22997) are attached to the task at
http://gna.org/task/?7415. The only difference with the original script is that the grace.view user
function calls have been removed, as these cannot be used in a system test.

Added systemtest Nmrglue.xtest_plot_hist_cpmg_several to test the histogram plotting of several spectra.

Task #7873 (https://gna.org/task/index.php?7873): Write wrapper function to nmrglue, to read .ft2 files and process them.
