<div class="block">A lifecycle callback that is called when a load is started.

 <p>Note - This may not be called for every load, it is possible for example for loads to fail
 before the load starts (when the model object is null).

 <p>Note - This method may be called multiple times before any other lifecycle method is called.
 Loads can be paused and restarted due to lifecycle or connectivity events and each restart may
 cause a call here.</div>
