* Factory to create {@link JsonObjectBuilder} and {@link JsonArrayBuilder}
* instances. If a factory instance is configured with some configuration,
* that would be used to configure the created builder instances.
*
*
* {@code JsonObjectBuilder} and {@code JsonArrayBuilder} can also be created
* using {@link Json}'s methods. If multiple builder instances are created,
* then creating them using a builder factory is preferred.
*
*
* For example:
*
*
* JsonBuilderFactory factory = Json.createBuilderFactory(...);
* JsonArray value = factory.createArrayBuilder()
* .add(factory.createObjectBuilder()
* .add("type", "home")
* .add("number", "212 555-1234"))
* .add(factory.createObjectBuilder()
* .add("type", "fax")
* .add("number", "646 555-4567"))
* .build();
*

* All the methods in this class are safe for use by multiple concurrent
* threads.
