Consistent quotes. I prefer doublequotes as Coffeescript assigns 

them a consistent meaning.

Changed the 'BINGO' algorithm to use just numeric coordinates, converting
exactly once from the BINGO to 0..4.

Changed the test-if-won algorithm to create scoped tests with consistent
signatures.  This let me catch an error I missed with the first pass.
