# More often than not at @RTR_tech, our ruby layer is a pass-through from our
# services to our client application.  In those cases, it doesn't make much
# sense to parse the JSON string.
#
# Other times, however, we want to work with the objects that come back, so
# like good ruby developers, we create classes which reflect the data we
# expect, but as an intermittant step, we convert the JSON to a Hash, which
# we convert to an object.
