Refactored Game Controller to now take array of ints and return array of
ints in order for the Game UI to interact with it

Note: Hint Pegs have three values
- 3 is WHite
- 2 is Black
- -1 is NO_VALUE (like null for int)

The mapping between color and int is stored in the enum class Pegs. More
refactoring should be done to clean up Game Controller. Create maybe a
Game Service or have conversion done in the Pegs enum
Modified Game to use GameController. Was not able to a launch it

NOTE: Working on code that works on your local machine with your own
packages resuts in issues when users pull rebase. Either add the files in
git so we can all use it or please clean up the code so as not to clutter
up the code base
