Added README.developers w/ initialisation instructions

    Initialising Source from Git Repository

    =======================================

This code uses `autoconf' and `automake' to generate the configure and

Makefile.in files needed to build the project. When the code is

distributed in tarballs these files are included and users only need

to run the standard `configure; make; make install' commands. For

users and developers who got the code from a git repository the

`autoconf' & `automake' tools will have to be used to initialise the

project. There are two ways of doing this, either by calling the tools

in the correct order or with the `autoreconf' tool, which hugely

simplifies the process.

  With `autoreconf'

  -----------------

For a first time initialisation the `autoreconf' tool needs to be run

with the `--install' argument to add a couple of necessary files.

    $ autoreconf --install

This only needs to be done once from a clean source directory. If any

changes are made to the autotools files the build files can be updated

with just

    $ autoreconf

  Without `autoreconf'

  --------------------

If the `autoreconf' command is not available if can be emulated with a

combination of several other commands. For the first time

initialisation the following commands need to be given in order:

    $ aclocal

    $ autoconf

    $ automake --add-missing

After any changes to configure.ac autoconf and automake need to be re-

run to pick up the changes

    $ autoconf

    $ automake

and after changes to any Makefile.am files automake has to be re-run

    $ automake
