Make(recipe)' - Construct a value and cache it

Usage examples:

        class MyComponent(binding.Component):

            # this makes a new dictionary in each MyComponent instance
            aDict = binding.Make(dict)

            # this makes an instance of 'thing.Thing' in each MyComponent
            aThing = binding.Make("things.Thing")

            # 1-argument functions are called with the MyComponent instance
            someAttr = binding.Make(lamdba self: self.otherAttr * 2)

            # Types and no-argument functions are just called
            otherAttr = binding.Make(lambda: 42)

Make accepts a binding.IRecipe (or object that's adaptable to one), and uses it to compute the attribute's value. See the docs for Descriptor and Attribute for the remaining semantics of this attribute type.

XXX need more docs for adaptations to 'IRecipe
