A global executor built on top of async-executor and smol
```
// spawn a task on the multi-threaded executor let task1 = asyncglobalexecutor::spawn(async { 1 + 2 }); // spawn a task on the local executor (same thread) let task2 = asyncglobalexecutor::spawn_local(async { 3 + 4 }); let task = future::zip(task1, task2);
// run the executor asyncglobalexecutor::run(async { assert_eq!(task.await, (3, 7)); }); ```
