An unavoidable task in our module creation is corralling our files into our module directory. We decided to multi-task and remove the files from our project while we place them in the module directory. In other words, we are just going to move the files from our project into the module. This is going to break the functionality temporarily. In a later task, we will take the necessary steps to make the job queue work again.
ScheduledJob.php, from your project model directory ch8 | Source Files | protected | models into your module model directory ch8 | Source Files | protected | modules | jobQueue | models.
