Description:

this class provides the basic functionality for DoubleLink-nodes.
DoubleLinks are abstract in that they do not provide a place for storing 
something, just the link-chains. So concrete linkedList elements
must subclass from me and add their value slots.

For more usability look at ValueDoubleLink or other subclasses.
