Complete reformatting of the base LaTeX files.

The paragraph structure has been changed so that each sentence now starts on a new line. This is
for better tracking of changes (via 'svn diff' for example), for better searchability of certain
text elements using command line tools such as 'grep', and for easier easier use of the 'sed' tool.
The change tracking is most important as it allows for finer granularity - a small change will now
only be shown as a change in one sentence rather than the whole paragraph, allowing the change to be
identified more easily. It also allows for easier commit maintenance.

Created two new LaTeX commands for improving the layout of Python code in the relax manual.

These are \pysep and \pyus which will be used to format the Python module separator character and
the Python underscore character respectively. They are used in the \module{}, \pycode{}, etc.
commands to add the '.\linebreak[0]' and '\_\linebreak[0]' text to allow for improved and consistent
line breaking.

Added the infrastructure for the unit tests of the specific_analyses.relax_disp.disp_data module.

This is in response to the post http://thread.gmane.org/gmane.science.nmr.relax.scm/19963/focus=5046
by Troels, and is described in my response at
http://thread.gmane.org/gmane.science.nmr.relax.scm/19963/focus=5048.

Updated the specific_analyses.relax_disp package __all__ list.

This was identified in the previously committed unit test.

Added the unit test infrastructure for testing the specific_analyses.relax_disp package.

This currently includes the package __all__ list unit test.

Created two new LaTeX commands for improving the layout of user functions in the relax manual.

These are \ufsep and \ufus which will be used to format the user function separator character and
the underscore character respectively. They are used in the \uf{} commands to add the
'.\linebreak[0]' and '\_\linebreak[0]' text to allow for improved and consistent line breaking.

Converted all LaTeX files of the manual to use the new \ossep and \osus commands.

This will result in better formatting of the manual by making the linebreaking after '/' and '_'
characters consistent and universal.

Created two new LaTeX commands for improving the layout of the relax manual.

These are \ossep and \osus which will be used to format the file and directory separator character
and the underscore character respectively. They will be used in the \file{} and \directory{}
commands to add the '/\linebreak[0]' and '\_\linebreak[0]' text to allow for better line breaking.

Improvement to the formatting of the GUI menu item text in the manual.

The text can now have a line break between the items, just after the arrows. This significantly
improves the paragraph layout in the manual.

Started to create the tutorial in the manual for using the dispersion GUI.

This is at the end of the relaxation dispersion chapter of the manual and covers the basic setup of
spin systems. It includes the recently added screenshots.
