Automatic Refactoring tool for Self 4.0

[ivan_r_moore]

Hello fellow Self interested people,

Guru - an tool for automated refactoring of Self programs
is now available from http://selfguru.sf.net

Given a collection of Self objects, Guru produces an equivalent set 
of objects in which there is no duplication of methods or certain 
types of expressions. To achieve this, Guru creates a replacement 
inheritance hierarchy and methods for factoring out expressions. 

Many thanks to Jecel Assumpcao Jr for helping test this
release.

Note that Guru currently only works for Self 4.0
A port to Self 4.1 in on it's way.

Ivan
