A JSON implementation of gCalAjax.

Modified by Kevin Kresge for better formatting, easier use, and performance.
Much thanks for Mark for his excellent work on this script!

To make this work, just call this script up wherever you want it to appear.
The included CSS file is set up for the Spry accordion divs, which you probably won't have
so just rename them to whatever div you intend to use.

The original script was actually this file, but you'd actually 
call the feed in the code rather than just inluding it in here.
This way, people cannot snag your email/group address out of the code
and start spamming you.
