PEP8 compliance and other code fixes

* Ran all the .py files in src/ and below through Yapf.
* Included some manual edits of core.py, this time successfully making
  two notorious sections a bit more pythonic than scheming.
* Left the module imports as is.
* This will be committed if it passes the most essential test:
  compiling, installing and running it.
