{- The following demonstrates the use of @massInput@.
@massInput@ takes as arguments:
- A configuration struct describing how the Widget should behave (how is the space of sub-forms structured, how many dimensions does it have, which additions/deletions are permitted, what data do they need to operate and what should their effect on the overall shape be?)
- Information on how the resulting field fits into the form as a whole (@FieldSettings@ and whether the @massInput@ should be marked required)
- An initial value to pre-fill the field with
@massInput@ then returns an @MForm@ structured for easy downstream consumption of the result
