# Focus on the initial spec.  Implement the simplest code to make the test pass. Once test passes, refactor the code to simplify. 
# Here are the specs:
# 1) Scoring basics - 10 frames, 10 pins used for scoring, minimum score is 0 and a max is 300. 
# 2) Implement basic scoring - 10 frames of 2 rolls each.  Normal rolls are 1 point per pin.
# 3) Strikes and spare strikes - 1 roll to knock all 10 are strikes (X), 2 rolls to knock all 10 are spares (/).
# 4) Scoring strikes - If first throw, (10+a).  If spare, 10 + a.  Max 30 for first, max 20 for second.
# 5) Focus on frames for scoring - score is a sum of individual frames.  Note: strikes causes frame crossover.
# 6) Implement spare scoring - Spare scoring crossing frames still count for that frame.
# 7) Scoring a strike - Finish implementing logic from #3.
# 8) Implement scoring considering strikes - Strike scoring crossing frames still count for that frame.
# 9) 10th Frame - If strike or spare is rolled, bowler gets extra ball.  This should make it 21 or less rolls.
