AreaField

This is your UITextView with only the text-entry functionality, so a multiline EntryField. Unlike the EntryField this does not support isMonetary or units.

AreaFieldDelegate

All of the text-entry relevant delegates are here.

Responder Behaviour

AreaFields behave the same way that UITextViews behave, becomeFirstResponder() will activate the field and resignFirstResponder() will deactivate the field.
