+ * 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.

+
+Although 1.6 compatibility is currently supported, it is not a project goal and may be
+removed in some future release.
+
+In compliance with RFC7159 page 10 section 9, the parser is more lax with what is valid
+JSON than the Generator. For Example, the tab character (U+0009) is allowed when reading
+JSON Text strings, but when output by the Generator, tab is properly converted to \t in
+the string. Other instances may occur where reading invalid JSON text does not cause an
+error to be generated. Malformed JSON Texts such as missing end " (quote) on strings or
+invalid number formats (1.2e6.3) will cause errors as such documents can not be read
+ reliably.
