I wrote this over the weekend and have found it tremendously useful already.  It&#x27;s very simple (less than 250 lines, nearly 100 lines of which is the template for HTML output), but it&#x27;s quick and easy to do large amounts of math.  I hope people give it a shot and enjoy it!  I&#x27;ll keep an eye on the comments; let me know if you run into any problems, or drop an issue into Github.
