This needs to be redesigned to account for all the related fields in a clean manner.
What we need here for starters is a repeater element, where each item has the following:
- Affiliations (could be more than one)
- Credit (could be more than one)
- Whether this author (ie. this item) is a corresponding author
There's a good chance we'll add more to the above, so we need a flexible design for this.
