Lucky Dollar Store Coding Challenge
-----------------------------------

The “Lucky Dollar Store” wants to test out a new loyalty program so that with each new purchase, a customer is automatically entered in a weekly raffle (one ticket per purchase). At the end of the week, several users can be chosen from a drawing to win giveaway prizes (depending how generous the manager feels).

They’ve hired you to implement this raffle and generously gave you these two functions they will be calling:

```
def record_customer_purchase(customer):
     # Fill this in


def run_weekly_raffle(num_winners):
     return winning_customer
```

Here are the specifics that they’re asking for:

- A customer can be entered in the same raffle several times
- Create a method so that a store manager can create a raffle ticket when a customer makes a purchase
- Create a method so that a store manager can draw X number of winners from the raffle pool (The same user cannot win multiple times in the same drawing)
- After someone wins, they cannot win again for the next 3 raffle drawings.
- Raffle tickets are reset between each drawing.

*No need to set up a database or store this information anywhere. This is an acceptable flow when the program runs.

Think about what classes you’d create, what data structures you’ll use, and how you’ll organize this program.
