Find slot fillers app

The code I wrote is in the package edu.knowitall.tac2013.findSlotFillersApp

The command line script runs as follows:

sbt 'run-main edu.knowitall.tac2013.findSlotFillersApp.findSlotFills entityName person/organization pathToOutputFile'

TODO:
  -Code only works for person entities currently
  -Need to look at demo code to see how to group together relations that are essentially the same
