Proof of concept: Automatically calculating coordinates from formulas.

This sample demonstrate how a simple Javascript can automatically interpret a formula in a web page and make it clickable so that it can easily be calculated on a mobile phone. Since many geocaching apps use web views to display the data, it should be easy to integrate.

This is just a demo. It's not perfect, but it's easy to use. Just keep tapping on the links. (Note: This was made for mobile devices where tapping is fast+easy.)
