Goal: The purpose of this lab is to demonstrate an understanding of constructors.

Problem: You are working in GMU's HR department. HR is responsible for tracking employee data to include: name, idNumber, department, and if orientation was attended. Whenever a new employee is hired, not all data is always available. You figure out data is always available in one of the following combinations:

- The ID number and name are known, but the department is not

- The ID number is known, but the name and department are not

- The ID number, name, and department are all known

If orientation was attended is never known. The following employees currently exist:

- ID: 5678. Name = Mary Contrary. The department is unknown

- ID: 1234; Name = Stu Dyalot; Department = AIT

- ID: 2468; Name = Julian Date. The department is unknown

Create an object-oriented solution to:

- Simulate the creation of these three employees with a message noting all employees have been loaded

- Creates a fourth employee from user input, entering only an ID number and name

- Provides a menu of all four employees with the opportunity to mark employees as having attended orientation, until the user indicates they are finished.
