      public EDI()
      Creates a new instance of EDI. Before consulting this instance, you must make sure that you use setColor(byte) and setTimeLimit(int). E.g., 
      VI edi = new EDI();

// Set the color of the player we want EDI to make decisions on behalf
// of.
edi.setColor(C.WHITE);

// Set the time alloted per decision.
edi.setTimeLimit(10); // 10 seconds

// Given a board state, have EDI recommend a move.
int move = edi.consult(state);
      The move result is encoded as an int. In order to make use of such a move, see the Move class which has static methods for getting details about the move.
