Change Description

Implements nasa/fprime#2592

[LeStarch]

First, let us be clear, this is top-rate work. It is also an implementation of a fairly critical subsystem. Thus I made a lot of comments. There is one thing I'd like you to think about: Error checking and resolution.

I want there to be a clear story on what happens and what is returned on malformed JSON data. Given what I see, it is probably a ValueError, or a custom MalformedDictionary error, or a combination. All other errors should be down-converted to a known set of expressive errors.

This will help a lot in determining what to do in the layer above and avoid the random exception problem.

Let me know if you have questions.
