First steps to operator after

[StoneCypher]

want to see it spin in node? do this

const jssm = require('.');
const sm   = jssm.sm;

const rgb = sm`red after 1s -> green after 4s -> blue after 5s -> red;`;

rgb.hook_entry('red',   () => { console.log(`entered red: ${  new Date().toLocaleString()}`); return true; });
rgb.hook_entry('green', () => { console.log(`entered green: ${new Date().toLocaleString()}`); return true; });
rgb.hook_entry('blue',  () => { console.log(`entered blue: ${ new Date().toLocaleString()}`); return true; });

won't merge until tests are written, but too tired to write tests rn
