> The difference algorithm aims at comparing two sequences of objects and
> return an "edit script" which represents how one can transform the first
> sequence into the second sequence. The script describes the various insert
> object, delete object and keep object commands. The script is guaranteed to
> be the shortest possible in terms of number of commands.
> From the script, one can either extract longest common sub-sequences (i.e.
> how similar the sequences are) or on the contrary the needed changes (i.e.
> how different the sequences are).
