Allow schema title to be used as class name (new useTitleAsClassname config option)

[jrehwaldt]

When having schemas where certain field names are repeated with different implementations the code currently generates unique class names such as Image__1, etc. I would like to have a configuration to use the title as class name instead.

So that

{
  "$schema": "http://json-schema.org/draft-04/schema#",
  "title": "SchemaTest body",
  "description": "Use title as class name.",
  "type": "object",
  "properties": {
    "image": {
      "type": "object",
      "title": "MyImage"
    }
  }
}

would result in

public class SchemaTest {

    private MyImage image;

    public SchemaTest() {
    }

    public SchemaTest(MyImage image) {
        super();
        this.image = image;
    }

    public MyImage getImage() {
        return image;
    }
}

public class MyImage{
}

Thank you for your great library. I am using it successfully and really like the RuleFactory design.

This has been asked for before. Interesting that in your design you expect "SchemaTest body" to become SchemaTest. Was that a typo or do you expect jsonschema2pojo to do some transformation/sanitization here?

In my implementation I only use the title for sub-hierarchies and stick with the filename otherwise. Not a deal breaker for me in general.

I would capitalize all first letters and strip spaces. Next illegal characters get replaced with underscore and that’s it.

I am willing to contribute PRs for all my requests if there’s a chance for approval.

Happy to accept a PR for this, as long as it is behind a configuration option, say, useTitleAsClassname. The default must be false.

Just saw your comment now. If you prefer a boolean property I can change it.

I implemented it as part of NameHelper for now. It seeemed the best place to me as it also works for enums this way.

Thank you very much! It was fun working on this one.
