 * Since we have no need to interact with the UI thread we can do all these
 * operations in the worker thread. We generally use the AsyncTask class
 * if we need to do something on the UI thread (ie update view) after
 * our long running task but since here we are only performing IO tasks
 * we don't need the UI thread to be involved
 *
 * we can launch like any other thread example usage:
 *
 * ThreadedIO ioThread = new ThreadedIO()
 * ioThread.start();
