GetChildren supported in Multi() operation?

[youngkin]

I need to get a node's children as part of a multi request. I've successfully used multi for DeleteRequest, but in looking through the code 2 things stick out:

1. While there is a getChildrenRequest, the struct isn't exported as is DeleteRequest. So I can't create a getChildrenRequest.
2. The zk.Multi() function checks for operation type and returns an error if the operation isn't one of DeleteRequest, CreateRequest, SetDataRequest, or CheckVersionRequest. So even if getChildrenRequest was exported zk.Multi() wouldn't accept it.

So, I just wanted to confirm that I'm correct in the above and whether or not there are any plans to support GetChildren as part of a Multi operation.
