Module builder 

ValColBuilder: the ContainerBuilder that feeds the dataflow input side.

Accepts flat (k, v, t, d) tuples via PushInto; when the internal tuple container reaches a threshold, sorts + forms a RecordedUpdates trie and queues it. finish produces one final trie from any remaining tuples.
