// The Critter interface defines the methods necessary for an animal to
// participate in the critter simulation.  It must return a character
// when getChar is called that is used for displaying it on the screen.
// The getMove method returns a legal move (one of the constants NORTH,
// SOUTH, EAST, WEST).  The x/y values passed to getMove represent the
// critter's current location in the world.
