Description:


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.


Instance protocol:

accessing
o  nextLink
return the next link

o  nextLink: aLink
set the next link

converting
o  asLink
