	CSGCamera provides a simple way to access the default sequence grabber component (say, an iSight or other DV camera).  To use:
16
	
17
	- Instantiate an CSGCamera instance (using the plain old -init method)
18
	- Set the CSGCamera's delegate using -setDelegate:.  The delegate is the object which will receive -camera:didReceiveFrame: messages.
19
	- Call -startWithSize: on the CSGCamera instance with a decent size (like 512x384).
20
	- Call -stop to stop recording.
