/**
 * This command is an alias to url and also a convenience method when called without any arguments in the sense that it performs a call to .url() with passing the value of `launch_url` field from the settings file.
 * Uses `url` protocol command.
 *
 * @example
 * this.demoTest = function (client) {
 *   client.init();
 * };
 *
 *
 * @method init
 * @param {string} [url] Url to navigate to.
 * @param {function} [callback] Optional callback function to be called when the command finishes.
 * @see url
 * @api protocol.navigation
