     * Originally from https://github.com/gmusick/jasmine-reporters. Adapted
     * to support file output via PhantomJS/Rhino/Node.js like JUnitXmlReporter.
     * Also fixed a couple minor bugs (ie month being reported incorrectly) and
     * added a few options to control how / where the file is generated.
     *
     * @param {object} [options]
     * @param {string} [options.savePath] directory to save the files (default: '')
     * @param {string} [options.filename] name of xml output file (default: 'nunit-results.xml')
     * @param {string} [options.reportName] name for parent test-results node (default: 'Jasmine Results')
