Ferreteria/v2/usage/forms

About

Forms in Ferreteria consist of several sets of classes that work together:

• control classes render editable (and eventually non-editable) data fields
• field classes handle translating values between internal storage and on-disk storage (database)

The Forms classes were rewritten from scratch in 2015; I'm designating this version 2. Version 1 is here, and notes on a possible version 3 are here.
