Expanded a comment about why 1 is subtracted in a test.

In the systemtest of -s Relax_disp.test_paul_schanda_nov_2015, added a test of counting the R2eff values.

This shows that the replicaceted R2eff at 950 MHz/4000 Hz point is overwritten.

A solution could be to change the dispersion frequency very little, to allow the addition of the datapoint.

Small fix for an example script.

Making sure that the replicated 4000 Hz point fpr the 950 MHz experiment is not overwritten.

Made additional check in sequence reading, that "nan" values are skipped.

Added systemtest relax -s Relax_disp.test_paul_schanda_nov_2015 -d.

This will cathc the loaning of "nan" values.

Added initial data for testing data from Paul Schanda.

This will demonstrate that there are several possibilities to enhance the r2eff point method.

Bug fix for the storage of the XML structural object in the state and results files.

Previously any objects added to cdp.structure (or any structure object) would not be saved by the
structural object to_xml() method unless the function is explicitly modified to store that object.
Now all objects present will be converted to XML.

Expanded the description of the sequence.attach_protons user function.

This follows from http://thread.gmane.org/gmane.science.nmr.relax.user/1849/focus=1855 .

Fix for the CSA constant equation in the model-free chapter of the manual.
