New Revision: 23415

URL: http://svn.gna.org/viewcvs/relax?rev=23415&view=rev
Log:
Added the 8th unit tests demonstrating edge case 'no Rex' failures of the 
model 'B14'.

This follows from the ideas in the post 
http://article.gmane.org/gmane.science.nmr.relax.devel/5858.
This is related to: task #7793: (https://gna.org/task/?7793) Speed-up of 
dispersion models.

This is to implement catching of math domain errors, before they occur.

These tests cover all parameter value combinations which result in no 
exchange:

    - dw = 0.0,
    - pA = 1.0,
    - kex = 0.0,
    - dw = 0.0 and pA = 1.0,
    - dw = 0.0 and kex = 0.0,
    - pA = 1.0 and kex = 0.0,
    - dw = 0.0, pA = 1.0, and kex = 0.0.
    - kex = 1e5,
