This project simulates the behavior of a single elevator.

• Python 3.7

• main.py
• ellevator.py
• readme.md

• Be sure you have installed Python 3.7 or higher and all files listed above are in the same directory
• In a Terminal shell, navigate to the directory chosen in the above step
• Type the command:

python3 main.py

• You will see text output in your terminal giving status info and prompting you for input. Respond accordingly
• Alternatively, you can run this from an environment of your choice. You will still run main.py to inititate the program

• When finished with its list of requests, the Elevator should return to the first floor (or lobby)
• There is only one Elevator
• There is only one master queue, which exists outside of and is accessed by the Elevator
• The Elevator accepts an input of (floor, direction) from the 'outside'. This summons the Elevator.
• The Elevator accepts an input of (floor, exit) from the 'inside'. This is logged as a destination.

• The Elevator moves incremenetally up and down along a list of integers between and including a provided minimum and maximum floor number. At each floor, the Elevator will decide if it should stop.
• The Elevator will stop at a floor if there exists an external summon request for the current floor in the same direction the Elevator is already traveling
• The Elevator will stop at a floor if there exists an internal request for the current floor, regardless of direction
• The Elevator will not stop at a floor if there exists an external summon request for the current floor in the opposite direction the Elevator is already traveling

• The Elevator can only accept input while the doors are open.
• The Elevator's behavior is hard-coded at the moment. It cannot quickly become another flavor of Elevator.
• The Elevator currently checks direction and if it should open its doors twice. This is in response to the decisions outlined above. I imagine there is a more efficient way to ensure the Elevator turns around at the top or bottom of its path, but I kept things simple for my and your (mostly my) sanity.
