------------------------------------------------------------

Attaching draft flex use for the facet.enum method.

This currently fails with:
{code}
SEVERE: Exception during facet counts:java.lang.IllegalStateException: external 
IndexReader requires skipDocs == MultiFields.getDeletedDocs()
        at 
org.apache.lucene.index.LegacyFieldsEnum$LegacyDocsEnum.reset(LegacyFieldsEnum.java:206)
        at 
org.apache.lucene.index.LegacyFieldsEnum$LegacyTermsEnum.docs(LegacyFieldsEnum.java:164)
        at org.apache.lucene.index.MultiTermsEnum.docs(MultiTermsEnum.java:276)
        at 
org.apache.solr.request.SimpleFacets.getFacetTermEnumCounts(SimpleFacets.java:566)
{code}

Not sure if that's an issue with all compound readers (top-level readers as 
opposed to segment readers) or if it's an issue with SolrIndexReader.

edit: this patch also makes BytesRef comparable.
