/**
 * Config generator.

 * We need to run integration tests on different versions of the Translator
 * library. This function allows for the Translator source file location
 * to be specified which is loaded onto the global namespace prior to the
 * test running.
 *
 * The library is provided as a UMD and so this logic could be moved to
 * the test file(s), which would need to be preprocessed by a module loader
 * like RequireJS. As we're already using Google Closure, that could get
 * complicated. Furthermore, if a future version of the library is not
 * provided as a UMD that approach may fail.
 *
 * This is a less DRY approach, but is both the simplest implementation as well
 * as (arguably) the more future-proof approach.
 *
 * @param {String} translatorFilename - The filename of the Translator library.
