[henshin-dev] Documentation

[Gregor Bonifer <gregor.bonifer@xxxxxx>]

Hi,

I added the documentation for the tree-based editor. I used DocBook as 
recommended in the eclipse wiki. To avoid having more than one entry in 
the online help I added a main documentation project henshin.doc. This 
project provides a main TOC with an anchor that can be used by other 
documentation projects to add entries to the main topic "EMF Henshin". 
This is done in the project henshin.editor.doc which provides the TOC 
generated from henshin.editor.doc.source. The help is available under 
Help > Help Contents > EMF Henshin. This document is also linked from 
the context help of the tree-based editor(F1) and the transformation 
wizard("?" button).

Regards,
Gregor
