Spawning

Spawning allows you to run a new asynchronous task in the background. This allows us to continue executing other code while it is running.

Say we have a webserver that wants to accept connections without blocking the main thread. We can do this by using the async_std::task::spawn function to spawn a new task that runs the connection handler. This function takes a future and returns a JoinHandle that can be used to await the result of the spawned task.
