Evaluate

Takes a string and evaluates it, thus giving the user an answer to a string such as "hsin(1)+hcos(1)", which will be e. The evaluator incorporates an error handler, as well as user entered constants. The function is in the module, easily made to be imported to other programs. A demonstration program is included an shows some possiblities. A help file is not included, but will be available by e-mail. An important point, to keep in mind, that almost all functions must be entered in form of sin(45). If a function has one argument, enter it like sin(45), otherwise, put first argument, function, second argument, as in 2+1.
