Title: cleanup of compiler.py

I had a hard time telling what was going on in the pipeline(s) assembly and run stage, so I did a tiny refactor on it. I think there is more logic than can be coalesced here, but I wanted to see if this form of change was at all agreeable to folks before stomping forward.

Includes:
* a new class _PipelineManager which deals with building and executing pipelines.
* rename/grouping of a couple of helper functions to more accurate names/places
* Doc-string format consistancy
* PEP8 blah blah

I want to add some documentation to this PR as well, especially around the _dispatcher class that I am having a hard time grocking.

Feedback welcome.
