Refactor Feed & Score Nodes

[seanmajorpayne]

What to refactor?

• app/scoring/score_nodes.py

Refactor reasons and solutions

• Score nodes presently use unconventional python naming with variables in ALL_CAPS format,
• has a few variables that are declared and never used
• does not use dependency injection as it should.
• it is only used by the feed but is located in the scoring folder so it should be relocated.
• Storing the climate feed into the db should not occur in this class.
• Feed uses some variables in ALL_CAPS, a generalized try/except to catch multiple types of errors,
• Imports are not in pep8 order & relative imports should be used when possible
• Both should use Pep 287 reST formatting for docstrings.
• We're passing a quiz_uuid to a query for a session_uuid in the localized graph function and this is bad!

Tests

• unit tests
