Hello,

I think that your request may be handled by one of two improvements:

1. Implement session support in ob-maxima.el; and
2. Many of the design decisions in the existing ob-maxima code should be
customizable.

I am attaching a patch to address 2. Please try it out, I think that it
will satisfy your requests. Feedback is welcome.
