Exercise : HarvardLawyer

• Write an employee class HarvardLawyer to accompany the other employees. Harvard lawyers are like normal lawyers, but they make 20% more money than a normal lawyer, they get 3 days more vacation, and they have to fill out four of the lawyer's forms to go on vacation. That is, the getVacationForm method should return "pinkpinkpinkpink".
• (If the normal Lawyer's vacation form ever changed, the HarvardLawyer's should as well. For example, if Lawyer's vacation form changed to "red", the HarvardLawyer's should return "redredredred".)
• Use the super keyword to interact with the Employee superclass as appropriate.
