Includes before extends in model

[query-string]

In some cases, includes must follow before extends. For example, https://github.com/ai/r18n gem requires 'include R18n::Translated' before I call 'translations' method.

My thought process here was somewhat hierarchical. First add functionality to the class then add functionality for instances.

Sometimes modules intended for inclusion will also extend the class. This is perfectly fine and should be OK to run after extend calls. The one caveat would be if an extend module has a dependency injected by an include module, but this should be an extremely rare case.

Remember that the model template is only a guide (with reasonable defaults). I still believe that extends belongs above includes in the guide as the default; however, it's certainly acceptable to bend the rule when needed.
