Add `@JsonWrapped`

[markwoon]

It would be nice to have the inverse of @JsonUnwrapped.

This would enable serializing this class:

class Gene {
  String symbol;
  String chrId;
  String chrName;
}

To this:

{
  "symbol" : "X",
  "chr" : { 
    "id" : "Y",
    "name": "chr1"
  }
}

I think use of JsonPointer expression would work well in expressing wrapping in JSON.
But how would one define grouping for fields to wrap? Something like..

@JsonWrapped({ @JsonWrapped.Group(path="/extra", fields={"b","c"}),
    @JsonWrapped.Group(path="/main", fields={"a"} })
public class Stuff {
   public int a, c, b;
}

to produce

{
   "main" : {
      "a" : 1
   },
   "extra" : {
     "b": 2,
     "c" : 3
   }
}

or such?

[markwoon]

Can it be built up as we go along?

class Gene {
  String symbol;
  @JsonWraped(path="/chr", name="id")
  String chrId;
  @JsonWraped(path="/chr", name="name")
  String chrName;
}

This would make it simpler to refactor code if we don't have to worry about updating the field name in the annotation.

I'd have to think about that, but my first thought was that it should be fine to use both @JsonProperty and @JsonWrapped to get this effect.

I really love JsonUnwrapped concept and find quite useful. JsonWrapped would be a great asset for project.
