Holiday Shopping Simulation

Takes in seven inputs from the user.

When debug mode is uncommented, a log of every customer arrival is printed, along with which cashier is servicing them. A percentage of these customers may then move to the gift-wrapping queue.

A statistical summary of the simulation is displayed, regardless of the status of debug mode.

Example run outputs:

num_cashiers = 2

total_sim_time = 1000

interarrival_time = 2

service_time = 5

giftwrap_time = 2

num_wrappers = 1

percent_wrap_service = 50
