Title: Changes about grading each question.

1. Changed the class name "Answer" into "MultiChoiceAnswer".
2. Added "private double score" in MultiChoiceAnswer FillInAnswer.
3. Made the "value" attribute of MultiChoiceAnswer to be the score.
4. Changed the format of FillIn and FillInAnswer, added sample method to
generate regex by keyword and also grade FillIn by matching userAnswer.
