New Revision: 23362

URL: http://svn.gna.org/viewcvs/relax?rev=23362&view=rev
Log:
Created the test_ns_cpmg_2site_expanded_no_rex8() relaxation dispersion unit 
test.

This is a demonstration commit, showing the 'NS CPMG 2-site expanded' model 
with no exchange when
kex = 1e5.  I.e. when the motion is too fast for exchange to be observed.  
This test should be used
for all dispersion models to make sure that they model this edge case 
correctly as well.

This follows from http://article.gmane.org/gmane.science.nmr.relax.devel/5906.
