Debugging and addition of the function 'disassemble_param_vector()' to the relaxation curve fitting.

Bug fix:

The indexing involved in the automatic generation of the user function component of the manual has
now been fixed. The bug was causing not all instances of the key words to be indexed. Now all the
minimisation algorithms are indexed.

Added 'make install' and 'make uninstall', changes to the installation chapter, and more indexing.

The installation chapter has been partially rewritten with the title changed, sections on the Linux
precompiled distribution, source distribution, and running a non-compiled version added, and Dasha
and Modelfree4 added to the list of optional programs. Indexing has been added to the chapter.

In the data analysis chapter, more indexing has been added.

In the makefile, the rules 'install' and 'uninstall' have been added. When 'make install' is typed,
the dir /usr/local/relax is made, all files are copied there, a symlink called /usr/local/bin/relax
is made to /usr/local/relax/relax, and the program is run with the test flag to generate the
byte-compiled *.pyc files. 'make uninstall' will delete the symlink /usr/local/bin/relax and the
directory /usr/local/relax.

I've started debugging the docstring extraction and formatting script docs/latex/fetch_docstrings.
The bug is only partially fixed.

Added a few indecies to the development chapter of the manual.

A make rule called manual_nofetch has been also created to compile the manual without getting the
docstrings from the user functions.

Added a section on the make system and makefiles to the development chapter of the manual.

Spell check and formatting fixes to the relax development chapter of the manual.

Removal of the style file.

Added a chapter to the manual for coding and the development of relax.

The current contents of the chapter is the text from the file 'docs/style'.

Moved all the temporary manual files out of version control.

Compilation of the manual is now by 'make'.

To create the PDF version of the manual, type 'make manual' in the base directory, while to create
the HTML version, type 'make manual_html'. The two scripts 'docs/latex/compile' and
'docs/latex/create_html' have been shifted into the new makefile 'docs/latex/Makefile'.
