native_binary() wraps a pre-built binary or script
in a *_binary rule interface. Rules like genrule
can tool-depend on it, and it can be executed with
"bazel run". This rule can also augment the binary
with runfiles.
native_test() is similar, but creates a testable
rule instead of a binary rule.

RELNOTES[NEW]: The new `native_binary()` and `native_test()` rules let you wrap a pre-built binary in a binary and test rule respectively.
