/**
* A {@code GetDataCallback} is used to run code after a {@link EasimartFile} fetches its data on a
* background thread.
*
* The easiest way to use a {@code GetDataCallback} is through an anonymous inner class. Override
* the {@code done} function to specify what the callback should do after the fetch is complete.
* The {@code done} function will be run in the UI thread, while the fetch happens in a
* background thread. This ensures that the UI does not freeze while the fetch happens.
*
*
* file.getDataInBackground(new GetDataCallback() {
* public void done(byte[] data, EasimartException e) {
* // ...
* }
* });
