A generator that replaces child nodes held by reference with ones held by value.
Use with compose_generators to forward that result to another generator.
Generators are intended for use as the first template parameter to the domain<> class template and control if and how expressions within that domain are to be customized. by_value_generator ensures all child nodes are held by value. This generator is typically composed with a second generator for further processing, as compose_generators<by_value_generator, MyGenerator>.
