+ * A JSON Pointer is a simple query language defined for JSON documents by

+ * 
+ * In a nutshell, JSONPointer allows the user to navigate into a JSON document
+ * using strings, and retrieve targeted objects, like a simple form of XPATH.
+ * Path segments are separated by the '/' char, which signifies the root of
+ * the document when it appears as the first char of the string. Array 
+ * elements are navigated using ordinals, counting from 0. JSONPointer strings
+ * may be extended to any arbitrary number of segments. If the navigation
+ * is successful, the matched item is returned. A matched item may be a
+ * JSONObject, a JSONArray, or a JSON value. If the JSONPointer string building 
+ * fails, an appropriate exception is thrown. If the navigation fails to find
+ * a match, a JSONPointerException is thrown.

+/**
+ * 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.
+ * <p>
+ * A JSONWriter 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 a cascade style. For example, <pre>
+ * new JSONWriter(myWriter)
+ *     .object()
+ *         .key("JSON")
+ *         .value("Hello, World!")
+ *     .endObject();</pre> which writes <pre>
+ * {"JSON":"Hello, World!"}</pre>
