Added keyword analyzer.
Merged wpwrapper and wputils into one class.
Added elasticsearch log to gitignore.
moved fieldsofstudy mapping and settings into elasticsearch.jhu.edu repo.
Added better labeling.
Unspecified post type for putOne -- now all post types can be put into elasticsearch instead of just fields of study.
If the post type hasn't been assigned to the settings property, exit out because this post type isn't being saved to elasticsearch.
