Create and react to reactive variables.

React to changes in reactive variables
Here's an example that shows how to make a reactive variable, change the
value every second, and make an automatically executed computation that logs
the value of the variable to the console any time the variable changes.
import {variable, autorun} from '@lume/variable'
const count = variable(0)
setInterval(() => count(count() + 1), 1000)
autorun(() => {
console.log(count())
})
This works because the autorun computation tracks which variables were used,
and tracks those variables "dependencies" or requirements of the computation.
When any dependency of a computation changes, the computation function will
be automatically re-executed.
