Drew Davenport 9a89ceff02 Rename PipelineCreator interface to Backend 
With the legacy Backend class renamed to CompositionPlanner, rename the
PipelineCreator interface to Backend. This interface maps most closely
to the concept of the "Backend".

Add some documentation to various Backend related classes.
