Beginning work on ticket charger
- right now just validates two things are present
- perhaps use virtus to be sure of the types?
Build up the ticket charger some more.
- #total returns the total price of all the tickets
- #external_charge_id= sets the external charge id on each ticket
- #charge! is responsible for telling the charger to actually charge stripe
	- not done yet
	- it will take the response returned from charger.charge! and set the external charge id
