/* All of the below is just to get the version number of the 3rd party library.
 * First we'll try to read it from package.json. This works when publishing or testing the package
 * but not when running an example app that uses a local copy of the package because the current 
 * directory will be that of the app, and it won't have package.json. Find the path of a file is hard:
 * http://stackoverflow.com/questions/27435797/how-do-i-obtain-the-path-of-a-file-in-a-meteor-package
 * Therefore, we'll fall back to GitHub.
 * We also don't have the HTTP package at this stage, and if we use Package.* in the request() callback,
 * it will error that it must be run in a Fiber. So we'll use Node futures.
