Created the infrastructure for the splitting up of the 'specific_fns.model_free' module.

The directory 'specific_fns/model_free/' has been created and the file 'model_free.py' has been
moved into it. To retain the same 'specific_fns.model_free' module namespace, the '__init__.py'
file of the new directory uses import statements.

Fixed a spelling mistake in the command line argument help system.

Added the svn:executable property to the unit test runner.

Addition of a sample script to create a Grace plot of Ix - Ix(theta).

This plot is the difference between the measured and back calculated peak intensities.

Merging of the 'error_import' branch.

The command used was:
svn merge -r3035:3073 svn+ssh://bugman@.../svn/relax/branches/error_import

These changes include the ideas which were discussed in the thread starting at
https://mail.gna.org/public/relax-devel/2007-02/msg00003.html (Message-id:
<45DACFEA.7020108@...>). The full details are given in the post located at
https://mail.gna.org/public/relax-devel/2007-03/msg00000.html (Message-id:
<7f080ed10703012125m7e6dff3du21e49d888cad2c02@...>).

Two major changes have occurred - the removal of the usage of the __builtin__ module for storage of
'global' variables; and a slight redesign of the RelaxError and RelaxWarning systems. If you would
like to use a RelaxError or RelaxWarning, the corresponding class must now be imported.

Extended the Grace plotting abilities to include series data such as relaxation exponential curves.

This patch includes a large number of changes. The 'grace.write()' user function docstring has been
updated and now includes the previously missing relaxation curve-fitting data type string matching
patterns.

In the module specific_fns.relax_fit the relaxation curve-fitting data type string matching patterns
have been updated to include the 'ave_intensities' series object (an array) and the 'relax_times'
series object. The 'self.return_grace_string()' method has been updated to include axes labels for
these objects. The 'self.return_value()' method of the specific_fns.base_class module has been
modified to check for data in 'self.relax.data' if the spin system specific data does not exist.

The relaxation curve-fitting sample script has been updated to create plots of the minimised
chi-squared value, the initial peak intensity, the relaxation rate, the average peak intensities,
and the normalised average peak intensities.

Plot normalisation is now supported for series-like data through the 'norm' argument to the
'grace.write()' user function. For relaxation curves, all plots will commence at the value of one.
This feature is useful for emphasising errors in the data sets.
