Example Application

[jacklinke]

Is your feature request related to a problem? Please describe.
It can be helpful when learning something new in programming - in addition to having documentation - to have a realistic example application to work with. For me, at least, this helps round out my overall understanding of how the concept works and fits into larger projects. I think this Issue would be an enhancement of #6

Describe the solution you'd like
A basic example app with a couple of automations demonstrating the bulk of the functionality provided by django-automations.

• Flesh out the examples already provided in the code.
• For simplicity in installation by the end user, perhaps include django-apscheduler or something similar as a dependency (calling AutomationModel.run() directly instead of using the management comnand).

Additional context
I will be happy to work on this (and have already begun to do so) if that works for you, @fsbraun.
