has_and_belongs_to_many not exercised #75
Description
While looking through the coverage reports, I noticed that HasAndBelongsToMany never comes up in the tests. I'm not super clear on what it does, and after tinkering around in the tests I wasn't able to get it to do anything other than throw exceptions. Would be super cool if someone could figure out what it's supposed to do, and how to test it.
@ipundit any interest?
