* Wrapper object that can represent any kind of basic REST object.
*
* This class is the result of a couple of design choices made in our REST
* data model. If could have been avoided if we used pointers all over
* the place and didn't rely entirely on the object specific implementations
* of deserializeFromJson and fromString to do the deserializing or everything.
*
* The assumption, though, was that most of the data we're dealing with has a
* known structure and maps to fixed types. So, the data model was optimized
* for that rather than flexiblity here.
