notes on the markup below...
onsubmit="clearDraft()" must be included in the form tag to clear the auto saved data when the form is submitted, otherwise
the next time the same user accesses this form for a new submission, the auto saved info will have populated the field.
you must specify a unique id for each element to be auto saved and this id must be added using the addElement method above
the generateScript method must be added after the page body, as shown below. This is required so that the auto save elements
are present before the script tries to populate them with the saved information.
