cart headers:
you can set these to which ever order you would like, and the cart will display the appropriate headers
and item info. any field you have for the items in the cart can be used, and 'Total' will automatically
be price*quantity.
there are keywords that can be used:
1) "_input" - the field will be a text input with the value set to the given field. when the user
changes the value, it will update the cart. this can be useful for quantity. (ie "Quantity_input")
2) "increment" - a link with "+" that will increase the item quantity by 1
3) "decrement" - a link with "-" that will decrease the item quantity by 1
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")
