Note: Rubocop complains about params option hash for some methods, these should be included in Style/OptionHash exceptions

Hey @danhealy thanks for this PR, it's looking good! I just wanted to check, are you able to see the travis CI failures?

Looks like it's a rubocop error, and then using #dig on a hash in one of the tests. We run the tests on ruby 2.2 so dig isn't a method yet.

@splybon Thanks for taking a look.

In my opinion, the Rubocop error for the Style/OptionHash issue should be ignored in this case as the parameters are being passed to the API as query parameters, and for at least one of the endpoints the options available are numerous. I will add this exception or change it based on your preference.

I hadn't seen the issue with dig -- I will change that.

@danhealy
Yes I agree with what you said about the rubocop error. Go ahead and disable that with the rubocop disable comment.

Thanks again for this PR, looks great! I finally got around to pulling it locally and testing it. I had 2 comments for it.
If you update it, we can get it merged in, and then there is another PR in that I would like to get merged so we can do a minor release.
