add Neo4jHandlers for all queries, though some lack an implementation
modify importer to take constructor arguments and read parameters from command line (rather than config file)
remove Config class & ServerStarter class from project
add directory with sample .csv files to import, along with tests to import these
update Neo4jDb to no longer use Config.class
add update handlers to CsvDb and NothingDb - they still don't exist for Neo4jDb
