Made new interface methods about move strategy implemented in the abstract PlayerImpl class instead of the HumanPlayer and ComputerPlayer
Removed double ; in Player interface
Create an OthelloBoardHandler factory
Created a greedy move strategy
Now PlayerImpl checks so that move strategy methods throws when type is HUMAN
Fixed misspelled
Formatted code
Changed place of conversion from Board to RectangularBoard. Now the strategy is responsible of creating a Board to send to the handler factory
