New Revision: 26806

URL: http://svn.gna.org/viewcvs/relax?rev=26806&view=rev
Log:
Added initial systemtest Nmrglue.xtest_plot_hist_cpmg to plot histogram of 
intensities.

This is dominated by the noise measurements.

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