Option to create constructors (with all fields, or with required fields)

[monksy]

At the moment it's a little messy with creating new instances of the POJOs with the builders. Could we get an option that would create an additional constructor to define the required fields?

Right now to create something of the following schema:

 Obj { name: asdf, age: 32; state:NC} 

You would have to invoke it by: (with builders enabled)

new Obj().withName("asdf").withAge(32).withState("NC")

Rather than [what I'm suggesting]

new Obj("asdf", 32, "NC")

I was just about to raise an issue similar to this. JSON-Schema (Validation) has the "required" keyword to signify which fields are mandatory for a schema object.

It would probably make sense support that rather than just adding an epic constructor with all fields.

So something like:

  {
    "type": "object",
    "$schema": "http://json-schema.org/schema",
    "description": "A thing",
    "id": "thing",
    "properties": {
      "id": {
        "type": "string"
      },
      "description": {
        "type": "string"
      }
    },
    "required": ["id", "description"]
  }

Should generate a constructor for (String id, String description) in the order specified.

Interestingly, I originally had "required": true" against each property in my schemas, however I see that required is not mentioned in the core JSON-Schema spec, tho jsonschema2java generates @NotNull annotations for those? That should probably also change. It looks like this may have changed in the draft-03 spec..
