[New Quizzes] Partial credit for formula questions
Formula questions currently are either right or wrong. Partial credit should be able to be awarded if students have gone some way to answering the question. For example:
A kettle rated `POWER` W takes `TIME` minutes to boil water. How much energy does the kettle transfer in Joules?
Full credit answer = POWER * TIME * 60 //Correct answer
Partial credit answer = POWER * TIME //Time not converted, but correct equation used
Allow for extra answers by having more "formula definition" fields. Different marks awarded for each, and different feedback for each. Another solution involves using pre-existing formula definition field. You can define multiple formulas to help compute an answer already. So, these mid-way formulas could be worth partial credit.
