I got the idea to SolutionChecker after some mails with
Jimmy Wales. I proposed to Jimbo setting up somthing to
collect math-exercises. He liked the idea and he asked me
whether I am a programmer.
As for programming I had not exactly thought of me. Jimbo,
in response maintained to be a very bad programmer, (ha ha).
How to proceed was not clear. I thought, hey, some bozo
should hack it in. As it turns out I am some bozo and
that's what you got.
