/* Go is a 2 player board game with simple rules. Two players alternate turns
 * placing stones on a grid. If a stone is surrounded on 4 sides by stones of
 * the opponent, it is captured. If a group of stones are surrounded, they are
 * captured.
 * See http://en.wikipedia.org/wiki/Rules_of_Go#Capture for a visual explanation.
 * 
 * Below is an implementation of a Go board. Please write some code in the
 * move() function to check for captures and output something when a capture
 * occurs. The sample moves represent a capture of two black stones.
