relax SVN archive

Bug fixes.

A number of bugs have been removed from the packaging script.

Further modification to the packaging script and added the program version to the manual.

The checked out repository is checked for changes before packaging.

A script has been created to make the file 'docs/latex/relax_version.tex', the contents of which are
included in the cover of the manual.

In the packaging script, the manual version is checked against the program version to see if they
match.

Finished the packaging script.

Updated the packaging script.

The relax version number is now checked.

Started to create a script for automatically packaging relax into a .tar.bz2 archive.

Added a proper version number string to the program and modified the initial relax printout.

Updated the manual and the release is really 1.0.6.

relax release 1.0.5.

This release includes both added features and bug fixes. The Euler angle beta of the diffusion
tensor is now treated as a glide reflection when between pi and 2pi rather than a translation of the
space between 0 and pi. The glide reflection and translation symmetries of the spheroid and
ellipsoid diffusion tensors are now collapsed such that all angles are between 0 and pi, and the
simulated values lie pi/2 either side of the fitted value.

Removed some debugging code.

Bug fix.

The module signal is no longer imported into the interpreter. Only ValueErrors are caught when
there is a failure in converting the Rex values into floats.
