Implementation of Pipeline and FilterHost interfaces. This is a large change, but all of the objects are interrelated.

I am also checking in a basic unit test that creates pipeline,
and the data source hangs during initialization.  The test sleeps one second and then stops the pipeline.

Andrew has already done a first pass on this, and the code has come largely from our working experimental branch.
