Initial steps in pursuit of PEP8 compliance.

Individual files were made compliant with PEP8 whenever possible, with
the exception of the long-line rule.  I'm not sure about how I feel
about that one yet.  The rest are fine with me.

Now that the code is PEP8 compliant, I need to change the design.
More changes for PEP8 compliance

Mostly fixed region.py but required changes in other files too.
More PEP8 fixes!

This should sum up the internal code changes.
Even more changes!

I give up on predicting the future.
Removed unused files.

These two files were no longer used.
Renamed files to lowercase.

Not yet sure about get_region.py instead of getregion.py.
Renamed commands and directories to lower case.

Also moved schematics into their own directory and cleaned up
an ancient file.
Merge branch 'feature/pep8-compliance' into develop
