#5 question pooling

[Larry Gray]

This is for when test become very large. We could randomly pick a %age of the number of question in the test file for questioning. What if we managed to get a test up to the size of 1000 questions? The only problem in doing a basic implementation of this is that a given test might pick too many questions from on area of the study, and yet leave other areas nearly or totally untested. Further enhancements would need to be made so that it would choose a %age of questions from each area.
