5220dbeffd beam/examples/beamsh: commands are messages.
Commands in the pipeline should either implement or pass-through command messages.

This amounts to a proof-of-concept implementation of the "pipeline"
design of Docker plugins.

f295ccc72a beam/examples/beamsh: basic implementation of the pipeline design, with static handlers for now.
In the pipeline design, several beam commands can be run concurrently,
with their respective inputs and outputs connected in such a way that
beam messages flow from the first to last. This is similar to the way
a unix shell executes commands in a pipeline: instead of STDIN and
STDOUT, each beam command has a "BEAMIN" and "BEAMOUT".

Since beam allows for richer communication than plain byte streams, beam
pipelines can express more powerful computation, while retaining the
fundamental elegance and ease of use of unix-style composition.
