1.4.0

• Providing dequeueSTM, isEmpty and isEmptySTM. Users can compose their own control queue with dequeueSTM and isEmptySTM.

• Removing enqueueControl: it appeared that PriorityTree is not suitable for control frames. 　For example, the dependency of all control frames is stream 0. So, PSQ does not contain multiple control frames at the same time. We removed enqueueControl. Users should prepare a queue for control frames by themselves.
