ContentStream Strategy

[Grant Ingersoll]

So, I'm working on SOLR-284 (Rich Documents, aka Tika) and I'm looking  
at the RichDocumentReqHandler included in that patch and I notice it  
has a lot of overlap with CSVRequestHandler and the  
XMLUpdateRequestHandler such that there seems to be a fair amount of  
commonality for dealing with the ContentStream.  Just look at their  
handleRequestBody implementations for those classes, they are almost  
identical.

Would it make sense to refactor these things into a base class and  
then have each implementation override a getLoader() method that took  
the base class delegates to?
