[gobo-eiffel-develop] Adding tree support to gobo

[Einar K. <eka...@cs...>]

Hello

I am/will be coding a small tree library using eiffel. As other parts of
my software use gobo I am trying to create it to be complicant with gobo
classes and if you want we can add it to the official distribution. At
the moment I plan to include binary search trees, splay trees and red
black trees.
