+/**
+ * A JSONArray is an ordered sequence of values. Its external text form is a
+ * string wrapped in square brackets with commas separating the values. The
+ * internal form is an object having <code>get</code> and <code>opt</code>
+ * methods for accessing the values by index, and <code>put</code> methods for
+ * adding or replacing values. The values can be any of these types:
+ * <code>Boolean</code>, <code>JSONArray</code>, <code>JSONObject</code>,
+ * <code>Number</code>, <code>String</code>, or the
+ * <code>JSONObject.NULL object</code>.
+ * <p>
+ * The constructor can convert a JSON text into a Java object. The
+ * <code>toString</code> method converts to JSON text.
+ * <p>
+ * A <code>get</code> method returns a value if one can be found, and throws an
+ * exception if one cannot be found. An <code>opt</code> method returns a
+ * default value instead of throwing an exception, and so is useful for
+ * obtaining optional values.
+ * <p>
+ * The generic <code>get()</code> and <code>opt()</code> methods return an
+ * object which you can cast or query for type. There are also typed
+ * <code>get</code> and <code>opt</code> methods that do type checking and type
+ * coercion for you.
+ * <p>
+ * The texts produced by the <code>toString</code> methods strictly conform to
+ * JSON syntax rules. The constructors are more forgiving in the texts they will
+ * accept:
+ * <ul>
+ * <li>An extra <code>,</code>&nbsp;<small>(comma)</small> may appear just
+ * before the closing bracket.</li>
+ * <li>The <code>null</code> value will be inserted when there is <code>,</code>
+ * &nbsp;<small>(comma)</small> elision.</li>
+ * <li>Strings may be quoted with <code>'</code>&nbsp;<small>(single
+ * quote)</small>.</li>
+ * <li>Strings do not need to be quoted at all if they do not begin with a quote
+ * or single quote, and if they do not contain leading or trailing spaces, and
+ * if they do not contain any of these characters:
+ * <code>{ } [ ] / \ : , #</code> and if they do not look like numbers and
+ * if they are not the reserved words <code>true</code>, <code>false</code>, or
+ * <code>null</code>.</li>
+ * </ul>

+/**
+ * A JSONObject is an unordered collection of name/value pairs. Its external
+ * form is a string wrapped in curly braces with colons between the names and
+ * values, and commas between the values and names. The internal form is an
+ * object having <code>get</code> and <code>opt</code> methods for accessing
+ * the values by name, and <code>put</code> methods for adding or replacing
+ * values by name. The values can be any of these types: <code>Boolean</code>,
+ * <code>JSONArray</code>, <code>JSONObject</code>, <code>Number</code>,
+ * <code>String</code>, or the <code>JSONObject.NULL</code> object. A
+ * JSONObject constructor can be used to convert an external form JSON text
+ * into an internal form whose values can be retrieved with the
+ * <code>get</code> and <code>opt</code> methods, or to convert values into a
+ * JSON text using the <code>put</code> and <code>toString</code> methods. A
+ * <code>get</code> method returns a value if one can be found, and throws an
+ * exception if one cannot be found. An <code>opt</code> method returns a
+ * default value instead of throwing an exception, and so is useful for
+ * obtaining optional values.
+ * <p>
+ * The generic <code>get()</code> and <code>opt()</code> methods return an
+ * object, which you can cast or query for type. There are also typed
+ * <code>get</code> and <code>opt</code> methods that do type checking and type
+ * coercion for you. The opt methods differ from the get methods in that they
+ * do not throw. Instead, they return a specified value, such as null.
+ * <p>
+ * The <code>put</code> methods add or replace values in an object. For
+ * example,
+ *
+ * <pre>
+ * myString = new JSONObject()

+     * performed and the one closest to the concrete class being serialized is used.
+     * If both annotations are at the same level, then the {@link JSONPropertyIgnore}
+     * annotation takes precedent and the field is not serialized.

+ * 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>
+ * <p>
+ * The first method called must be <code>array</code> or <code>object</code>.
+ * 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.
+ * <p>
+ * This can sometimes be easier than using a JSONObject to build a string.
