Description:

A DiffPatch has a collection of DiffChunks, and a collection of corresponding 
SequenceableCollection snippets. It can be used to patch a file (= SequenceableCollection) 
forwards or backwards.



[instance variables:]
    chunks:         <SequenceableCollection of DiffChunk->DiffChunk>
    snippets:       <SequenceableCollection of SequenceableCollection->SequenceableCollection>

Instance protocol:

 applyTo: file

Applies this patch to the given collection. Makes no sanity checks on the contents of the collection - simply blindly applies the chunks and snippets to its argument.

 initChunks: c file1: f1 file2: f2

 invert

Causes this patch to invert itself; if previously it represented the changes from file1 to file2, after being sent #invert, it will represent the changes from file2 to file1. After inversion, calling #applyTo: on file2 will yield file1, rather than the other way around.
