Board.java

Added a move method to whiteMarbles haven't had time to test it. Someone please run a few checks as follows:
1) In the main method call the select function 1 or more times on valid marbles to be selected from the white marbles
2)run move(i,j) where i,j is a valid play field for moving the marbles(Note that the move should be happening by taking the closest marble to that field so I guess if there are two marbles which are equally close to a field something interesting would happen but I really don't have the time to test now)
3)you should have a System.out for 3 marbles which I have selected, modify it to see if everything is working fine
