Re: Euphoria MVC framework - template parser online

I added another example for the template engine.

The use of functions makes the code look a little busy right now, but I'll be adding "map properties" to the parser, where you retrieve nested values, e.g. item.propery_name, etc.

Heck, as it is right now, you could just use this template parser right now to separate your logic and presentation layers for a basic website.
