Add SolrDoc and SolrElementField class.
Add a new class SolrFieldParser and remove some classes like GenericIndex.
include class diagram for components in the cn-index-processor packaage (dataone), metacat, and solr library.
added more classes to the index diagram to reflect current state of the code - needs to be updated to include plan for implementation (e.g., DocType object is not what we want). http://bugzilla.ecoinformatics.org/show_bug.cgi?id=5884
enable plantuml generation when building the sphinx documentation. note that you do need to have graphviz installed, but hopefully that is all.
add solr index documentation outline. http://bugzilla.ecoinformatics.org/show_bug.cgi?id=5884
