Metacat

add fieldsToMerge property for annotation updates

add stub merge method to match Skye's recent refactoring to support reindexing when deletes are performed.

use refactored classes from cn-index-processor. still in flux, but improving to better handle non-xml files

add accessors for bean property

use ISolrDataField because RDF subprocessor uses the SparqlField subclass.

use input stream instead of Document for resource map processing test

update classes and context files that use cn-index-processor classes. allowing document subprocessors to be less tied to XML.

use sparql field and triple store from cn-index_processor (refactor). include annotatorSubprocessor for testing in metacat-index

let metacat-index lookup annotations for indexing rather than the metacat "reindex" action.

when we remove a slor index of a resource map, we don't need to know the content of the resource map. Instead, we will search the solr index to get information.
