 * Class TicketIdentityGenerator

 * Generates a short (7 character identifier)

 * 10^-6 prob of collision for approx 1500 tickets, should be adequate for most events.
 * Purchase Id is also used when modifying tickets online so collisions are only really an issue for manual check ins
 * this problem can be resolved by using a sufficiently smart human.
