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.

Added functionality to lib/io to extract a list of file basenames and a list of fileroot matching a pathname pattern.

This can be useful when loading many spectra and assigning spectrum IDs.

Expanded the histogram plotting to add initial gauss distribution.

This shows that the gauss distribution should be fitted, instead of just calculating the gauss distribution from the Full width at half maximum (FWHM).
