The addUncompressed function is for node-only, and is a temporary workaround until we expose a better crypto interface in both node and the browser. I wrote tests for this function that were node-only, but were broken in the browser. I also wrote tests for the Point class that should have worked in both node and the browser, and did, but I was using the wrong module such that it worked only in node. This update makes the tests work in the browser by using the correct module.
