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
Coveralls wear rails.
Get the external charge id from the charge.
Add stripe.
Plan for a charger collaborator.
Begin implementation of charger
- need to handle failure
- added empty charge class because virtue wants it
- charge needs to be defined still
Add some stripe responses we can test against.
