SignatureUpdateProcessorFactory questions

[Erik Hatcher]

I was just tinkering with creating a simple update processor (coming  
soon in a new JIRA issue) and used SignatureUpdateProcessorFactory as  
a starting example.  A couple of things I noticed:

  - several methods are overridden, but are basically just deferring  
to what the base class already does (processDelete,  
processCommit...).  Perhaps these should simply be removed?

  - the loadClass method does a Class.forName - but this will only  
work when the class is in solr.war, not if it is coming from the Solr  
home lib/ subdirectory.  Shouldn't SolrResourceLoader be used instead?
