Class LinkableObject

object --+
         |
        LinkableObject

Known Subclasses:

An object that allows to link its attributes to attributes of other objects via a Link object. For instance:

   p = LinkableObject()
   p.x = Link(o,"name")
   print p.x

links attribute x of p to the attribute name of object o.

p.x will contain the current value of attribute name of object o.

If the value of getattr(o, "name") is callable, p.x will return the return value of the call.
