Streams

shtk.Stream instances are pairs of file-like objects (one for reading data from the process, one for writing data to the process) used for communication with running processes. If a stream is one way (e.g. FileStream) then the underlying file-like objects reader or writer may be handles to os.devnull.

shtk.Stream instances are usually constructed internally within SHTK, rather than being directly instantiated by the end user.
