public interface IGuessEvaluator

Evaluate a guess made by the user against the target word. That is, count the number of partial matches and exact matches. See the package overview for more information about matches.

Hints:

• Choose two non-alphabetic characters, say '*' and '-'. Make a copy of the two words to compare. Substitute '*' for each exact match, effectively preventing another match with that character. Then substitute '-' for each partial. Finally, count the number of occurrences of each character.
• This problem is tricky!
