1. Create a single server customer object, and create a queue simulation as follows.
   1. Set a min/max service time range for the Customer Object
   2. Create 20 Customer objects, and have 5 objects randomly exceed the top limit bounds of their service time.
   3. Have the Customer objects enter the queue at random times
   4. Track the time when the customer enters the queue, begins service, and exits the queue. (this is the end service time)
   5. Use these values to calculate q-hat and u-hat based on some T(n) (Note: your choice of T(n) may still have customers waiting in the queue; this is OK)
   6. Calculate the standard deviation of the service times from 0 to T(n)
   7. Run some simulations of the code, and report what happened. Can you explain why?
