boulder - like a builder but heavier

This provides two main traits and associated derive macros:

• Buildable, which lets you set complex default values, and then customise only the fields of interest for a given instance.
• Generatable which lets you set default sequences for each field, and then override only the particular sequences of interest.

These traits pass-through Option<T>, Cell<T>, RefCell<T>, Rc<T>, Arc<T> and Mutex<T> in the sense deriving Generatable or Buildable for T automatically gives you default generators and builders for all of these simple wrappers.

If you enable the persian-rug feature, you get two new traits:

• BuildableWithPersianRug, which lets you build instances which belong to a persian_rug::Context.
• GeneratableWithPersianRug, which lets you generate instances which belong to a persian_rug::Context.

These traits pass-through all the same all the same wrappers as the base traits, but additionally Proxy<T>.
