Subject: [PATCH] fixed uniqueid so that it is a function as expected by
 index.js and elsewhere

also added test for uniqueid. only test that two calls to uniqueid return unique enties. had to modify the output slightly and added a counter to the system otherwise two back to back calls would return the same value.
