Description

With LUCENE-1516, IndexWriter.getReader, we take over the
instantiating of IndexReaders which prevents users who have
implemented custom IndexReader subclasses from using them.

The patch will create an IndexWriter.setReaderFactory method and
a IndexReaderFactory class that allows custom creation of the
internal readers created by IndexWriter.
