[Dev] writing extension parcels

[Philippe Bossut]

I plan to give a try at writing an hCalendar parcel:
- user give a URL of a page embedding hCalendar events (vevent)
- parcel load and parses the page, creates a collection and creates on 
Chandler event for each vevent
- if time allows, defines an asynchronous task to refresh events 
regularly (similar to what the feed parcel tutorial does)

That would allow a user to "subscribe" to an event page and see those 
events overlayed in Chandler in their own calendar.

hCalendar is specified here:
    http://developers.technorati.com/wiki/hCalendar

Further, we can do similar parcels to support other microformats:

Cheers,
- Philippe
