/**
* JSONStringer provides a quick and convenient way of producing JSON text.
* The texts produced strictly conform to JSON syntax rules. No whitespace is
* added, so the results are ready for transmission or storage. Each instance of
* JSONStringer can produce one JSON text.
*
* A JSONStringer instance provides a value method for appending
* values to the
* text, and a key
* method for adding keys before values in objects. There are array
* and endArray methods that make and bound array values, and
* object and endObject methods which make and bound
* object values. All of these methods return the JSONWriter instance,
* permitting cascade style. For example,
* myString = new JSONStringer()
* .object()
* .key("JSON")
* .value("Hello, World!")
* .endObject()
* .toString(); which produces the string
* {"JSON":"Hello, World!"}
*
* The first method called must be array or object.
* There are no methods for adding commas or colons. JSONStringer adds them for
* you. Objects and arrays can be nested up to 20 levels deep.
*
* This can sometimes be easier than using a JSONObject to build a string.
