* New `build_mf` namespace for the multi-function builders. * The type name of the created multi-functions is now "private", i.e. the caller has to use `auto`. This has the benefit that the implementation can change more freely without affecting the caller. * `CustomMF` does not use `std::function` internally anymore. This reduces some overhead during code generation and at run-time. * `CustomMF` now supports single-mutable parameters.
