Detailed Description

Restricts types to those which can construct flox::RegistryInput values.

A flox::registry_input_factory is a type that can construct flox::input_preferences_typename instances.

A flox::registry_input_factory must provide a using input_type = <TYPENAME>; declaration to indicate the type of flox::input_preferences_typename it produces. It must also provide a mkInput function that constructs an instance of the declared input_type from a name and a flox::RegistryInput.
