+/**
+ * JSONWriter 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
+ * JSONWriter can produce one JSON text.
+ *
+ * A JSONWriter 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 a cascade style. For example,
+ * new JSONWriter(myWriter)
+ * .object()
+ * .key("JSON")
+ * .value("Hello, World!")
+ * .endObject(); which writes
+ * {"JSON":"Hello, World!"}
+ *
+ * The first method called must be array or object.
+ * There are no methods for adding commas or colons. JSONWriter adds them for
+ * you. Objects and arrays can be nested up to 200 levels deep.
+ *
+ * This can sometimes be easier than using a JSONObject to build a string.
