 * A Node is an entity containing both a data object and a pointer
 * to another node, considered this node's successor. A Node has the 
 * following methods:
 * 
 *   Node(Object obj)          - makes a node containing obj
 *   Object getData()          - returns the node's data object
 *   void setData(Object obj)  - sets the node's data to obj
 *   Node getNext()            - returns the node's successor
 *   void setNext(Node next)   - sets the node's successor
