Made WeakHashMaps to avoid memory errors
Clear hashmaps for every new query and remove synchronized calls
Put entity filter last in the filter list because that is the one that uses coref chains from stanford. That is where all the memory and speed problems come from
Made StanfordAnnotationHelper a lazy val
Changed from WeakHashMap back to HashMap
moved the clearing the hasmaps to the correct place. It was clearing after every slot, but it should be clearing after every kbp query
Put a length limit on the size of the document for coref at 100000 characters
Added more memory in Build.scala
Reduced the lsit of coref docs to 20 with maximum character amount at 20000, approximately 10 pages of text
Started a file for calculating doc size statistics
Catch an exception in KBPQueryExecutor and print the nil for that query
