/**
* Listens for events on this task.
*
* Events have three callback functions (referred to as `next`, `error`, and
* `complete`).
*
* If only the event is passed, a function that can be used to register the
* callbacks is returned. Otherwise, the callbacks are passed after the event.
*
* Callbacks can be passed either as three separate arguments <em>or</em> as the
* `next`, `error`, and `complete` properties of an object. Any of the three
* callbacks is optional, as long as at least one is specified. In addition,
* when you add your callbacks, you get a function back. You can call this
* function to unregister the associated callbacks.
*
* @example **Pass callbacks separately or in an object.**
* ```javascript
* var next = function(snapshot) {};
* var error = function(error) {};
* var complete = function() {};
*
* // The first example.
* uploadTask.on(
* firebase.storage.TaskEvent.STATE_CHANGED,
* next,
* error,
* complete);
*
* // This is equivalent to the first example.
* uploadTask.on(firebase.storage.TaskEvent.STATE_CHANGED, {
* 'next': next,
* 'error': error,
* 'complete': complete
* });
*
* // This is equivalent to the first example.
* var subscribe = uploadTask.on(firebase.storage.TaskEvent.STATE_CHANGED);
* subscribe(next, error, complete);
*
* // This is equivalent to the first example.
* var subscribe = uploadTask.on(firebase.storage.TaskEvent.STATE_CHANGED);
* subscribe({
* 'next': next,
* 'error': error,
* 'complete': complete
* });
* ```
*
* @example **Any callback is optional.**
* ```javascript
* // Just listening for completion, this is legal.
* uploadTask.on(
* firebase.storage.TaskEvent.STATE_CHANGED,
* null,
* null,
* function() {
* console.log('upload complete!');
* });
*
* // Just listening for progress/state changes, this is legal.
* uploadTask.on(firebase.storage.TaskEvent.STATE_CHANGED, function(snapshot) {
* var percent = snapshot.bytesTransferred / snapshot.totalBytes * 100;
* console.log(percent + "% done");
* });
*
* // This is also legal.
* uploadTask.on(firebase.storage.TaskEvent.STATE_CHANGED, {
* 'complete': function() {
* console.log('upload complete!');
* }
* });
* ```
*
* @example **Use the returned function to remove callbacks.**
* ```javascript
* var unsubscribe = uploadTask.on(
* firebase.storage.TaskEvent.STATE_CHANGED,
* function(snapshot) {
* var percent = snapshot.bytesTransferred / snapshot.totalBytes * 100;
* console.log(percent + "% done");
* // Stop after receiving one update.
* unsubscribe();
* });
*
* // This code is equivalent to the above.
* var handle = uploadTask.on(firebase.storage.TaskEvent.STATE_CHANGED);
* unsubscribe = handle(function(snapshot) {
* var percent = snapshot.bytesTransferred / snapshot.totalBytes * 100;
* console.log(percent + "% done");
* // Stop after receiving one update.
* unsubscribe();
* });
