moved/copied some files for backup
changed some scaffolding lines

modified wording of the scaffolding
added maker getter function

Now the cond is randomly selected based on how many subjects completed
each cond -- but need to test whether this works correctly!
Got mmturkey script to work

added settimeout function and experiment.end function
now performs debug mode and shows what would have been submitted to
mturk
Q:
1) how to link it to actual mturk
2) how to make sure the make getter does not decrement if not a real
worker? refer to Molly's code next.function
