// TODO: Let's start sketching our ticket store!
//  First task: implement `IntoIterator` on `TicketStore` to allow iterating over all the tickets
//  it contains using a `for` loop.
//
// Hint: you shouldn't have to implement the `Iterator` trait in this case.
//   You want to *delegate* the iteration to the `Vec<Ticket>` field in `TicketStore`.
//   Look at the standard library documentation for `Vec` to find the right type
//   to return from `into_iter`.
