[ZDP] New paragraph

[Maik Roeder]

Hi !

I have added a new Paragraph ZClass to the ZDP-Tools:

The ZClass Documentation can be found here:
http://zdp.zope.org/projects/zdptools/DocumentFolder/ParagraphClass

     Paragraphs can be added to any object, but should not be added to 
     Paragraphs themselves, because Paragraphs are the smallest editable
     unit besides the abstract and content.

     All Paragraphs are listed below the abstract and content DTML-Methods.
     The content and abstract will still remain valid, and the paragraphs can
     be mixed with them, or used as an alternative. 

     This ZClass allows a finer granularity of content ownership. So, you
     can work with multiple people on a document, and each person can still
     hold ownership of the part. 

     It is also better for longer documents, because these can be split into
     several parts, and you don't have to scroll to far in the browser to get
     to the part you want to change. 

     It is planned to allow references to Links and Snippet between the 
     Paragraphs. This way, Links and Snippets, don't have to be hardcoded in
     a text, but can be included dynamically. Possibly all documents will need
     to get a unique id, so a Catalog search can find them for easy inclusion. 

     The contextorder attribute will allow changing the order of paragraphs
     and all intermixed objects. 

Greetings,
