* This is essentially a mix of K2Node_BaseAsyncTask::ExpandNode and K2Node_SpawnActorFromClass::ExpandNode.
* Several things are going on here:
* -Factory call to create proxy object (K2Node_BaseAsyncTask)
* -Task return delegates are created and hooked up (K2Node_BaseAsyncTask)
* -A BeginSpawn function is called on proxyu object (similiar to K2Node_SpawnActorFromClass)
* -BeginSpawn can choose to spawn or not spawn an actor (and return it)
* -If spawned:
* -SetVars are run on the newly spawned object (set expose on spawn variables - K2Node_SpawnActorFromClass)
* -FinishSpawn is called on the proxy object
*
*
* Also, a K2Node_SpawnActorFromClass could not be used directly here, since we want the proxy object to implement its own
* BeginSpawn/FinishSpawn function (custom game logic will often be performed in the native implementation). K2Node_SpawnActorFromClass also
* requires a SpawnTransform be wired into it, and in most ability task cases, the spawn transform is implied or not necessary.
