    "array"   : [1,2,3],
    "hash"    : {"one":{"two" : 2}}
    }
]
puts @obj.at_json_path("number")
=> 1
puts @obj.at_json_path('array')
=> [1,2,3]
@obj.at_json_path('hash.one')
=> {'two' => 2}

##Note on Patches/Pull Requests

• Fork the project.
• Make your feature addition or bug fix.
• Add tests for it. This is important so I don't break it in a future version unintentionally.
• Commit, do not mess with rakefile, version, or history. (if you want to have your own version, that is fine but bump version in a commit by itself I can ignore when I pull)
• Send me a pull request. Bonus points for topic branches.
