    - added code for Item class
    - added inventory to Room objects

    Modified by dklick 2018-02-10
    - added equality operator overloads
    - added inequality operator overloads
    - added code for pseudo-NULL items
      - NULL_ITEM
      - NULL_ROOM
      - NULL_PATH
    - modified to store objects rather than pointers in the linked list
    - modified to use the subscript operator overload in the linked list

    This is the implementation file for a Dungeon object. It also
    serves as the implementation file for Room, Item, and Path objects.
