[Axiom-developer] changes

[root]

A newer set of changes has been checked in.

There is a change to the src/doc/book.pamphlet due to discussions and
work by C Y Student, David Mentre, and Bertfried Fauser. The book now
renders graphics and is suitable for bulding under pdflatex. More
graphics needs to be added but this has not yet happened.

The various 'echo' messages at the start of each stanza have been
cleaned up. These are unimportant except as a debugging tool. The
echo messages for each directory contain a unique number (that may
be changed across updates but will be unique). The unique number 
allows you to find the exact failing stanza along with a trivial
statement of what the stanza is trying to achieve.

The major change is that src/graph now exists. The graphics portion
of the system now exists. It is not yet connected to the axiom
interpreter and is still undergoing changes. Most of the files
are now in pamphlet format. I've documented the file formats 
for the 2D case in src/graph/fileformats.pamphlet
(see mnt/linux/doc/src/graph/fileformats.dvi). You can test this
version in a newly built system by typing:

export PATH=$AXIOM/bin:$PATH
cd int/graph
viewAlone parabola

You should see a graph of a parabola. If you click on the graph you
will get the menu. To quit, click twice on the quit button in the
bottom right corner of the menu. The viewAlone program has been
modified to output detailed information from the graph files.

The 3D case should also work but I have to reverse engineer the
process and document it, develop a test case, etc.

Calls from the Axiom interpreter do not yet work because I need
to set up sman (superman) which is the overall process that gets
invoked in the axiom script. I'm working on that.

If you happen to download and build the system, please try it
and give me feedback.

Work continues.
