import java.util.LinkedList;


/* -------------------------------------------------------------------------------------------
 *
 *  This class will be used to manage the State for each movement performed 
 *      Getters:
 *          getWorldArray() -> returns the 2D array (String[][])
 *          getInitEndPointCount() -> returns the initial number of end points (int)
 *          getPath() -> returns the current path taken by the player (LinkedList<Directions>)
 *          getPlayer() -> returns the player of that current state (Player)
 *      Other methods:
 *          printPaths() -> print the path taken by the player (void)
 *          addPath() -> add a direction to the current path taken by player (void)
