// CSE 142 Homework 8 (Critters)
// Authors: Stuart Reges and Marty Stepp
//
// This is the superclass of all of the Critter classes.  Your class should
// extend this class.  The class provides several kinds of constants:
//
//    type Neighbor  : WALL, EMPTY, SAME, OTHER
//    type Action    : HOP, LEFT, RIGHT, INFECT
//    type Direction : NORTH, SOUTH, EAST, WEST
//
// Override the following methods to change the behavior of your Critter:
//
//     public Action getMove(CritterInfo info)
//     public Color getColor()
//     public String toString()
//
// The CritterInfo object passed to the getMove method has the following
// available methods:
//
//     public Neighbor getFront();         returns neighbor in front of you
//     public Neighbor getBack();          returns neighbor in back of you
//     public Neighbor getLeft();          returns neighbor to your left
//     public Neighbor getRight();         returns neighbor to your right
//     public Direction getDirection();    returns direction you are facing
//     public int getInfectCount();        returns your current infect count
//                                         (# of Critters you have infected)
