/**
* A {@code FunctionCallback} is used to run code after {@link EasimartCloud#callFunction} is used to
* run a Cloud Function in a background thread.
*
* The easiest way to use a {@code FunctionCallback} is through an anonymous inner class. Override
* the {@code done} function to specify what the callback should do after the cloud function 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.
*
* For example, this sample code calls a cloud function {@code "MyFunction"} with
* {@code params} and calls a different function depending on whether the function succeeded.
*
*
* EasimartCloud.callFunctionInBackground("MyFunction"new, params, FunctionCallback() {
* public void done(EasimartObject object, EasimartException e) {
* if (e == null) {
* cloudFunctionSucceeded(object);
* } else {
* cloudFunctionFailed();
* }
* }
* });
*
*
* @param
* The type of object returned by the Cloud Function.
