Overview

TODO The one problem I have with this is that when a field is empty, we still

save the record to the database.  The difficulty is that when the 
form is displayed, you need to have all the records there, ones that
were saved and empty ones for those not saved, all in the proper order.
This presents a challenge I'm not willing to tackle at this moment.
But it should be done so that the database isn't cluttered with needless
records.

Note: We serialize the data. This makes it easy to store checkbox arrays, dates, etc, without having to worry about munging the data first.
