[Axiom-developer] MathML package

[Arthur Ralfs]

I've posted my MathML package on SandBoxMathML.
I'm still working on both the code and the documentation but
it does work now.  I've also included the diff files needed to
patch Axiom so it can be built with mathml as a new output
form.  There are also a few files to help with viewing the
output in Firefox.
