+    Imports and cleans dictionary files provided by WordNet 3.0
+
+    Download dictionary file (look for "DATABASE FILES ONLY" package):
+
+    http://wordnet.princeton.edu/wordnet/download/current-version/
+
+    Decompress and copy data.adj, data.adv, data.noun and data.verb files 
+    to same directory as this script, then run:
+    
+    $ node import.js 
+    
+    This will produce a words.txt dictionary file of 4-10 letter words 
+    to be used by batch.js puzzle generator.
