Remove empty file.

While it may have been planned this would contain
tests for the main() function, I'm not convinced this
is useful above the cli tests.
Add a helper class for Proton boilerplate.

This moves the Proton work into a helper, and tests it separately
from the scoring logic. This helper could probably be extracted later
if desired, but for the moment sits here.

Also move a per-team result helper to the helpers.
Add a note about how to run the tests.
Add Travis CI support.

For all the testing.
