This class is registered as singleton and allows you to batch activities. Once captured as a batch these activities can be pulled back up as a group.

```php
LogBatch::startBatch();

LogBatch::getUuid(); // 15c72460-4998-49ac-a0a3-647cc6f312ef

$log = activity()->log('log look mom, I did something...');
$author = Author::first();
$author->delete(); // deletes books too

Activity::latest()->get();
// Author Deleted,  batch_uuid: 15c72460-4998-49ac-a0a3-647cc6f312ef
// Book 1 Deleted,  batch_uuid: 15c72460-4998-49ac-a0a3-647cc6f312ef
// Book 2 Deleted,  batch_uuid: 15c72460-4998-49ac-a0a3-647cc6f312ef
// log look mom, I did something..., batch_uuid: 15c72460-4998-49ac-a0a3-647cc6f312ef
$log->batch_uuid; // 15c72460-4998-49ac-a0a3-647cc6f312ef
