client = Riak::Client.new()
bucket = client.bucket('MyBucket')
my_json_obj = bucket.get('MyKey')
my_json_obj.content_type #=> "application/json"
my_json_obj.data.to_json #=> {"name":=>"Joe"}
my_json_obj.data.to_s #=> nameJoe
Should RObject.data.to_s be aliased to .to_json when we know the content_type is json?
