Added helper functions for calculating tfidf values
query database for master list of words
added function to add labels
added a recursive batchInsert function that calls itself once the previous doc insert is completed
recursive function can add multiple documents without conflicts (currently db is wiped clean before starting)
added three json files for batch test. Need to be able to read directory like web historian
added 4 dummy json files to test, batchInsert is currently recursive
created function to update specific properties on a node through neo4j batch operations
word connections are updated on both database and server side, can calulate IDF value now
adds in real tf values onto relationships between documents and word nodes
