Summary:To support native modules in web workers, native modules need to have an notion of the JS executor/thread that called into them in order to respond via Callback or JS module call to the right executor on the right thread.
ExecutorToken is an object that only serves as a token that can be used to identify an executor/message queue thread in the bridge. It doesn't expose any methods. Native modules Callback objects automatically have this ExecutionContext attached -- JSModule calls for modules that support workers will need to supply an appropriate ExecutorToken when retrieving the JSModule implementation from the ReactContext.
