Stray puts

Fix tests, add to CHANGELOG, squash commits please.

We might need to drop some old(er) rubies to get a build going and possibly lock some gems. Let us know if you can't do it part of this PR, I can take a look at some point.

[jufemaiz]

@dblock not sure why - this was a straight branch from master here.

ruby-1.9.3p551 https://travis-ci.org/codegram/hyperclient/jobs/153170104

Installing ruby_dep 1.4.0
Gem::InstallError: ruby_dep requires Ruby version >= 2.2.5, ~> 2.2.
Using hashdiff 0.3.0
Using uri_template 0.7.0
Using metaclass 0.0.4
Using powerpack 0.1.1
Installing json 2.0.2 with native extensions
Gem::InstallError: json requires Ruby version ~> 2.0.

Features are failing, not sure why (again, this was a straight branch from here):

[dblock]

As I said, we're bringing newer dependencies in (gems don't check in a Gemfile.lock), and some things no longer work.

I've fixed the build in #105, you can rebase.

Danger and build still not happy. See above.

[jufemaiz]

@dblock the problem is the delegation to the children directly as per https://github.com/codegram/hyperclient/blob/master/features/steps/api_navigation.rb#L45-L46 + https://github.com/codegram/hyperclient/blob/master/features/steps/api_navigation.rb#L51

I can't find the approach used to go from the Hyperclient::Resource directly to the embedded elements "posts". It's got something to do with the outcome of the method_missing (https://github.com/codegram/hyperclient/blob/master/lib/hyperclient/resource.rb#L84-L94) function returning nil.

[dblock]

Can't you just implement to_h and to_hash explicitly? Or skip these in method_missing?
