Purpose:
    This program simulates the Skyborne Express Company's alien pet delivery system. 
	It allows the user to manage deliveries of extraterrestrial pets 
   	using a singly linked list implemented in the AirshipOrderList class. 
    Users can add, modify, find, remove, and display deliveries interactively.
Command Parameters:
    -
Input:
    Customer name (string)
    Alien pet name (string)
    Quantity of pets (integer)
    Total cost of delivery (double)
    Menu choice (integer)
Results
    Confirmation messages for each operation (add, modify, remove)
	All of the information of the delivery that the user searches.
	Displays an error message if the user inputs the wrong menu choice.
Notes:
    The program flow is as follows:
	1. Display a welcome message and list available alien pets.
    2. Show the main menu with options to manage deliveries.
    3. Take user input for menu selection.
    4. Perform the selected operation:
        - Add a delivery
        - Modify an existing delivery
        - Find a delivery
        - Remove a delivery
        - Display all deliveries
    5. Loop until the user selects exit (-1).

	It uses fun, creative alien pet names for simulation purposes.
