com.barrybecker4.game.twoplayer.common.search.tree.SearchTreeNode
Represents a move/node in the game tree. Each SearchTreeNode contains a Move as its userObject. When showing the game tree graphically, these variables can take a lot of space since they are in every node in the tree. Still it is better to have them here than in the move structure so that when we are not in debug mode the space is not used. @author Barry Becker
