"""Sets up widgets to collect input on a view.
See `setUpWidgets` for details on `view`, `schema`, `prefix`,
`ignoreStickyValues`, `names`, and `context`.
`source`, if specified, is an object from which initial widget values are
read. If source is not specified, the view context is used as the source.
`degradeInput` is a flag that changes the behavior when a user does not
have permission to edit a field in the names. By default, the function
raises Unauthorized. If degradeInput is True, the field is changed to
an IDisplayWidget.
`degradeDisplay` is a flag that changes the behavior when a user does not
have permission to access a field in the names. By default, the function
raises Unauthorized. If degradeDisplay is True, the field is removed from
the form.
Returns a list of names, equal to or a subset of the names that were
supposed to be drawn, with uninitialized undrawn fields missing.
