Provide static factory methods for JsonArray

[ralfstx]

Ideally, these factory methods should support varargs. Not sure about the method name.

JsonArray.createArray( 1, 2, 3 );

Or should the methods go to JsonValue to be next to valueOf( ... )?

JsonValue.createArray( "a", "b", "c" );

Or on a Util class like so:

Json.createJsonArray( 1, 2, 3 );

For the sake of keeping minimal-json minimal, a util class Json would look the very least attractive to me. Since you already have collection type-specific factories such as JsonArray.readFrom, my favorite would be JsonArray.createArray. Need an assignee?

@sbandara Actually, I have this idea of a Json class for quite some time and find it more and more appealing for the reasons outlined in #52.

Need an assignee?

Implementation is the least of all efforts, but I'm thankful for thoughts and discussion!
