Dependency	sequelize
Current Version	3.30.4

The version 4.0.0 is not covered by your current version range.

Without accepting this pull request your project will work just like it did before. There might be a bunch of new features, fixes and perf improvements that the maintainers worked on for you though.

I recommend you look into these changes and try to get onto the latest version of sequelize.
Given that you have a decent test suite, a passing build is a strong indicator that you can take advantage of these changes by merging the proposed change into your project. Otherwise this branch is a great starting point for you to work on the update.

Does this merge mean sequelize-cli will create models appropriately for sequelize@4.0.0? There's one breaking change I've been beating my head against recently.

"classMethods and instanceMethods are removed."

If sequelize-cli truly supports sequelize@4.0.0 the model template needs to move the associate function outside of classMethods, which was removed.

Here's someone doing a similar change in the sequelize/express-example:

sequelize/express-example@0745b9d

Here's the template that needs to be updated.

https://github.com/sequelize/cli/blob/master/lib/assets/models/model.js

Please tell me yes/no if sequelize-cli should support sequelize@4.0.0 like this. I understand it's a forward-moving, breaking change!
