/**
 * 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.
