A number of cosmetic changes to the 'error.py' file (addition of comments and removal of spaces).
I mentioned these changes within the post located at
https://mail.gna.org/public/relax-devel/2006-08/msg00082.html (Message-id:
<7f080ed10608292250u3bc0a0b0ud7a319e05ee70f28@...>).
I've added a number of comments to both the RelaxError and RelaxWarning systems. There were also
a large number of empty lines with trailing white-space that I've cleaned up as well. This may make
the merging process a little more difficult.
