simplified presentation of response results

[glenwiley]

There is some concern that developers using the API might find it unpleasant to wade through the response data specified in the description so there might be room to offer the results in a more easily digestible format.

One approach would be to offer an entry point that returns the data as a struct, another approach would be to offer a helper function that extracts a specific piece of data from the response (such as the IPv4/6 address from an A record).
