-# We modify Hash to add a few features we need:
-#
-# * sorted output of keys to in yaml.
-# * reference values either with hsh[key] or hsh.key
-# * deep merge
-# * select fields
-#
-# Because the json parsing code we use doesn't support setting a custom class, it is easier for us to just modify Hash.
