> Config binding helpers (components that add macros to the pystachio
> config language) were registered in a way that used self-construction. 
> In practice, binding helpers need initialization that comes from command-line parameters. With the implicit construction method, we can't provide construction parameters to the helpers.
> We need to switches to an explicit construction/registration, instead
> of auto-construction when the class is registered. (Interestingly, this
> is the way that the documentation on the binding helpers code says that
> it works!)
> Instead of writing:
>          FooHelper.register()
> We should write:
>         BindingHelper.register(FooHelper())
> Which makes it possible to do:
>        BindingHelper.register(FooHelper(url=bar))
