+/**
+ * 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> <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> <small>(comma)</small> elision.</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>Values can be separated by <code>;</code> <small>(semicolon)</small> as
