Modified the Sconstruct script to load the entire program only when fetching the docstrings.

Bug fixes due to unstable, broken Numeric Python packages:

Fixed a bug in the minimisation code. The Cholesky Hessian modification was failing due to the
Numeric Python package instability. The code should catch if the Cholesky factorisation fails and
then modify the factor tau and repeat the steps until the factorisation is succesful. Previously
the Numeric 'cholesky_decomposition()' function would throw out the "LinearAlgebraError" error, but
now something else is thrown out! The code now handles any error.

A bug fix to the Newton minimisation code has also been added. When the print flag is set above 3,
the code tries to calculate the eigenvalues of the Hessian. However the Numeric function
'eigenvectors()' is completely broken and causes any code which calls it to hang infinitely. The
code has been commented out.

A complete shift from the make build system to the scons build system (and a bug fix).

All the targets of all makefiles have been rewritten into python functions within the Sconstruct
file 'sconstruct'. Now instead of typing 'make install', you type 'scons install'. Hence, all
makefiles have been deleted.

The executable python script 'docs/latex/fetch_docstrings' has been moved to the non-executable file
'docs/latex/fetch_docstrings.py'. It is now imported into the Scons python script 'sconstruct' and
hence '__init__.py' files have been added to the 'docs' and 'docs/latex' directories.

The script 'docs/latex/version' has been shifted completely into the 'sconstruct' file and has been
deleted.

The file 'docs/release_checklist' has been modified to use the scons rather than make commands.

The script 'package' which was made redundant by the original shift to the make system has been
deleted.

Bug fix: The file 'generic_fns/palmer.py' has been modified to gracefully handle a Modelfree4 bug
whereby the 'mfout' output file has been corrupted due to the fusion of columns.

Rewrote the whole sconstruct script.

The script now executes a class which does all the work.

The 'install' target is half written.

Fixed the Mac detection in the Scons script.

Added the ability of the Scons script to catch Mac OS X.

The linker is then sent the options '-bundle -bundle_loader /usr/bin/python -dynamic' to create the
OS X shared library. Not sure how well this will work.

Removed the '.so' part of the shared library target for compatibility.

Added all the necessary code to the Scons script to build the relaxation curve fitting C module.

Added the shell of an Scons script.

Changed the one line program description.
