+/**
+ * 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.
+ * <p>
+ * A JSONStringer instance provides a <code>value</code> method for appending
+ * values to the text, and a <code>key</code> method for adding keys before
+ * values in objects. There are <code>array</code> and <code>endArray</code>
+ * methods that make and bound array values, and <code>object</code> and
+ * <code>endObject</code> methods which make and bound object values. All of
+ * these methods return the JSONWriter instance, permitting cascade style. For
+ * example,
+ * 
+ * <pre>
+ * myString = new JSONStringer().object().key(&quot;JSON&quot;).value(&quot;Hello, World!&quot;)
+ *         .endObject().toString();
+ * </pre>
+ * 
+ * which produces the string
+ * 
+ * <pre>
+ * {"JSON":"Hello, World!"}
+ * </pre>
+ * <p>
+ * The first method called must be <code>array</code> or <code>object</code>.
+ * 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.
+ * <p>
+ * This can sometimes be easier than using a JSONObject to build a string.
+ *
