Title: Implement callbacks for Models

Callback Models:

```ruby
[
:before_validation,
:around_validation,
:after_validation,

:before_save,
:around_save,
:after_save,

:before_create,
:around_create,
:after_create,

:before_update,
:around_update,
:after_update,

:before_destroy,
:around_destroy,
:after_destroy
]
```

Each of those takes a symbol, which is the name of the method.
