Further develop the classes Vehicle, Car, Bicycle and TestVehicles to include following: ( Codes for classes are found in the bottom of post) Vehicle:

- Add new datamember, CalendarBuyingDate which specifies when vehicle is bought ( current date in constructor for simplicity).

- Implement Comparable and Clonable interfaces in Vehicle class. Comparable should sort vehicles by price.

- Cloneable should call super.clone() to get a shallow copy of the object, and clone all "mutable" objects the class contains to get a deep copy.

(Mutable objects are objects wh can be changed without it beeing created a new copy. String is immutable, while Calendar is mutable.)

Car and Bicycle:

- Create your own version of clone method to make a deep copy.

TestVehicles:

- Should be given an extra choice, "Test clone method" to test the clone method. This test can be hardcoded, and should create new car, make a copy of it, and be able to edit date on one of the objects without affecting the other. Print both car object with date as verification.
