Node server to support medic-webapp.
Currently supports auditing by proxying requests to CouchDB and updating the audit history where required.
Get node deps with npm install.
Export a COUCH_URL env variable so sentinel knows what database to use. e.g.
export COUCH_URL='http://root:123qwe@localhost:5984/medic'
node ./server.js
TEST_ENV=1 grunt test
