* Used in the Add External Form process. This generates a JS object that maps "raw" field types to those

*
* Any fields that aren't mapped to a "raw" field won't get listed here. They can be used when editing forms,
* but not when initially adding them. Also, for Option List fields (checkboxes, radios, dropdowns, multi-selects),
* this function ONLY returns those custom fields that specify an Option List. Without it, the user wouldn't be
* able to map the options in their form to an Option List associated with a field type.
