RDFa to iCalendar service.

The PHP script wil scrape an HTML page or fragment for iCalendar data expressed as RDF in attributes (RDFa), and give back an iCalendar file.

It's supposed to work as an endpoint.

It currently follows the model described here: http://www.coreymwamba.co.uk/testbed/caltest2.html which is a vendor-agnostic way of annotating events to HTML using RDFa.
