Feature Request: Support DataContract or JsonProperty Attributes for mapping

[ravensorb]

For applications that already have a large data model, it would be very helpful to be able to reuse existing attribute notations instead of needing to add yet one more attribute on the data model classes. Any chance you would consider supporting either (or both) the DataContract attributes or JsonNET attributes for class/property mappings? This would make it easier to use the library without adding it as a hard dependency to multiple class libraries.
