[Catalyst] Ajax

[Daniel McBrearty]

I also like jquery a lot. Choice of js library has abig effect on this
stuff, and jquery has some nice functions for handling it.

AJAX is just a matter of having requests that update part of a page
asynchronously - not really directly connected to Cat/templating. It's
a question of how you structure your pages and the mapping of
functions to uri's.

If you search the list archives you will find some discussions of ways
to implement this in cat, using the architecture intelligently,
though.
