Playing around with nodes process -- a not very robust CLI script that will export CouchDB view as a static JSON file

vwToJson.js

* View-to-JSON CLI script for Node, turns a CouchDB view into a static JSON file.

* Example Useage: node vwtojson.js username password view filename directory server port
