### The Meaning of `coroutine.yield();`

`coroutine.yield()` is a special statement that must be called inside of while loops.
`coroutine.yield()` is a special statement that must be called inside of while loops that are inside of a command.

It allows for commands to run in parallel, while ensuring that background tasks
(like motor safety checks) are run.
An analogy would be the sips of water you take while you finish your homework.

An analogy would be taking turns in a bowling alley, where players (commands) take turns one at a time to bowl the ball (run the command) for each mechanism, and each mechanism is its own lane.

The `coroutine` object contains many other useful methods that can only be called
inside of commands.
