Creating Employee objects
myEmployee details:
firstName = A
lastName = M
myOtherEmployee details:
firstName = B
lastName = N
myEmployee.ToString() = Employee
myEmployee.GetType() = Employee
myEmployee.GetHashCode() = 58225482
Employee.Equals(myEmployee, myOtherEmployee) = False
Employee.ReferenceEquals(myEmployee, myOtherEmployee) = False
