+/**
+ * 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().put("JSON", "Hello, World!").toString();
+ * </pre>
+ *
+ * produces the string <code>{"JSON": "Hello, World"}</code>.
+ * <p>
+ * The texts produced by the <code>toString</code> methods strictly conform to
+ * the JSON syntax rules. The constructors are more forgiving in the texts they
+ * will accept:
+ * <ul>
+ * <li>An extra <code>,</code> <small>(comma)</small> may appear just
+ * before the closing brace.</li>
+ * <li>Strings may be quoted with <code>'</code> <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>
+ * <li>Keys can be followed by <code>=</code> or <code>=></code> as well as by
+ * <code>:</code>.</li>
+ * <li>Values can be followed by <code>;</code> <small>(semicolon)</small> as
+ * well as by <code>,</code> <small>(comma)</small>.</li>
+ * </ul>
