More work on differential equations

I continued to have problems with maxima. I decided to change direction. Now working on the program (still in Ruby) to generate code for any of Ruby, Ruby with my APFP, Maple, or (hopefully) Maxima. I’ve switched the environment from Linux to Vista as well, as that is where I have Maple. I had a earlier version (in Unicon) which would generate code in either Unicon or Maple, so I have a good idea of what I am doing.
