Class fraction

[jatkinson1000]

Adds the functionality of giving the 'fraction through a classification' a score is based on the handicap.

As requested by users.

Should probably use type of classification in the function name for consistency elsewhere. No other schemes can use this at present, but field will need it in #46

[jatkinson1000]

Need to add a check for when handicap and score can overlap slightly either way at boundaries after being rounded to integers.

Roughly:

• If score is a boundary value (in classification_scores) set to... 0.0? 1.0?... 0.0 makes sense I think as 1 occurs when we are at the highest classification we can be.
• Though on this note check what to do when we hit the top bound - should always be 1.0

Think this is now OK to go.
Consider bumping to 1.1.0 and adding a release, or instead wait until larger changes such as #46 come in.
