				changes the value, it will update the cart.  this can be useful for quantity. (ie "Quantity_input")

			4) "remove" - a link that will remove the item from the cart 
			
			5) "_image" or "Image" - the field will be an img tag with the src set to the value. You can simply use "Image" if
				you set a field in the items called "Image".  If you have a field named something else, like "Thumb", you can add
				the "_image" to create the image tag (ie "Thumb_image").
				
			6) "_noHeader" - this will skip the header for that field (ie "increment_noHeader")
