/* --------- Adds custom fields using filters. ------ 
The below custom fields shows various types one can use.
It is then displayed in the backend Order Details page and in admin and customer e-mails.
Checkboxes by default result only show the number 1 when clicked. I have added code so that when the a checkbox is clicked it will
show text such as On and Yes. Checkbox is also pre-selected.
