County selector working.
Separated openlayers and ext concerns by performing a callback-oriented refactoring. First pass at modifying parser to permit rows of length > 2.
Removed old mocks. Added new mock. Switched code to work with new mock.
Added four tests. Squashed one bug.
Squashed parser tokenization bug exposed by excess whitespace in mock. Used opportunity to make parser more robust while still fulfilling original use case.
