Please don't. As quite a lot of people have pointed out, a calculator parser 
is pretty easy to do.

Send me some description on what is needed and where it should fit in, and I 
offer to make the code during the next week. The most difficult thing in 
doing this will be to figure out the koscript code/api, writing the actual 
parser is not a problem.
