## Job API

#### execution()

Allow to wait to execution of a task.

```js
    const job = new Job({command, path, params});
    setTimeout(()=>{
      job.emit('executed');
    },500)
    await job.execution();
    console.log('500ms later. Do other stuff')
```


#### getResults()

Tries to get the results, waits for execution before retuning it

```js
    const job = new Job({command, path, params});
    setTimeout(()=>{
      job.emit('executed');
    },500)
    const res = await job.getResults();
    console.log('500ms later. Do thing with res')
```
