All Please describe the feature requested. Some APIs wrap the JSON data in the response. For example, Google Latitude wraps its data in a "data" key. According to a developer on the Google group, .NET webservices wrap the data in a 'd' key. To make life easier for Google APIs, we implemented JsonCParser which enables the developer to not have to declare to wrapper classes.

We should generalize it so it can be used across all cases, allowing the data/error wrapper key to be specified when constructing the JsonObjectParser. We should use the builder pattern to ensure thread safety. By default it would assume that there is no data/error wrapper key, but if you use the builder you can override that, e.g.: new JsonObjectParser.Builder(JsonFactory).setDataKey("data").setErrorKey("error").build()
