New Revision: 3341

URL: http://svn.gna.org/viewcvs/relax?rev=3341&view=rev
Log:
Application of Sebastien Morin's docstring and comments patch.

For the patch, see the post at 
https://mail.gna.org/public/relax-devel/2007-07/msg00038.html.

This patch (patch_consistency_tests__l1.2_r3340__docstrings_and_comments) 
corrects docstrings and
comments errors which were remnants of the jw_mapping code from which the 
consistency_tests code was
inspired. Also, this patch adds docstrings and comments to the code for 
making it easier for users
to understand what the code actually does.
