Build and Run

To build and run jar file

Can Be improved

• For BucketFill command is used recursion which can be replaced with non-recursive implementation using stack.
• I have used mutable approach for Drawing part but now i am thinking that immutable would be better, however i dont want to refactor everything again now, as not much time left, happy to do that if you are interested though
