singleStudentDataObj

This pull request includes a potential fix for querying the database repeatedly each time
we need a value to pre-fill the form. I also fixed a "doing it wrong" error WordPress reported
with a call to wp_enqueue_script().

The solution turned out to not be quite as straight-forward as I'd hoped, but I learned even
more about how WordPress works - so that's good. I needed to tweak which action hooks are used
for the **studentData** and **requireAuthentication** objects as well as the priorities of those
actions.
