REWORKED: Extensively reworked to remove the "reverse engineering" method of matching a fieldname to an actual survey question. Now uses the new functions in common.php to generate an array of every fieldname that SHOULD be in the survey responses table, and can then match up the appropriate qid, answercode by searching that array. This has decreased file size by 10k (about 1 third). Would appreciate testing by others, but works well with my test survey data.
