    this class provides the basic functionality for Link-nodes.
    Links are abstract in that they do not provide a place for storing 
    something, just the link-chain. So concrete linkedList elements
    must subclass from me and add their value slots.
    
    For more usability look at ValueLink or other subclasses.
