Would like to contribute Content Indexer and Extractors

[ryan]

Hi All,
 
I finally finished implementing the text extractors for slide.  I have a
TextContentIndexer that uses the extractor framework to extract text and
index it with lucene, and I have a TextContainsExpression that wires it
to DASL for searching.  
 
I have extractors for:
 
MS Word
MS Excel
MS PowerPoint
PDF
 
I would be happy to contribute it all.  How do I do that?
