Jared Beck ad3806fcbb An idea to combat model pollution
Problem
-------

`has_paper_trail` adds too many methods to the ActiveRecord model.

> If I'm counting correctly, installing the paper_trail gem adds 36 instance
> methods and 10 class methods to all of your active record models. Of those
> 46, 13 have a prefix, either "pt_" or "paper_trail_". I don't know what the
> best way to deal with this is. Ideally, we'd add far fewer methods to
> people's models. If we were able to add fewer methods to models, then I
> wouldn't mind prefixing all of them.

Solution
--------

Add only two methods to the AR model.

1. An instance method `#paper_trail`
2. A class method `.paper_trail`

The instance method would return a `RecordTrail` and the class method would
return a `ClassTrail`. Those names are totally up for debate.

Advantages
----------

- Plain ruby, easy to understand
- Adding new methods to e.g. the `RecordTrail` does not add any methods to
  the AR model.
- Methods privacy is more strongly enforced.
- Enables isolated testing of e.g. `RecordTrail`; it can be constructed with a
  mock AR instance.

Disadvantages
-------------

- Two new classes, though they are simple.
