-/**
- * 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
- * coersion 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
- * well as by <code>,</code> <small>(comma)</small>.</li>
- * <li>Numbers may have the <code>0-</code> <small>(octal)</small> or
- * <code>0x-</code> <small>(hex)</small> prefix.</li>
- * <li>Comments written in the slashshlash, slashstar, and hash conventions
- * will be ignored.</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
- * coersion for you.
- * <p>
- * The <code>put</code> methods adds values to 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 sysntax 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>
- * <li>Numbers may have the <code>0-</code> <small>(octal)</small> or
- * <code>0x-</code> <small>(hex)</small> prefix.</li>
- * <li>Comments written in the slashshlash, slashstar, and hash conventions
- * will be ignored.</li>
- * </ul>

-/**
- * JSONStringer 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
- * JSONStringer can produce one JSON text.
- * <p>
- * A JSONStringer 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 JSONStringer instance,
- * permitting cascade style. For example, <pre>
- * myString = new JSONStringer()
- * .object()
- * .key("JSON").value("Hello, World!")
- * .endObject()
- * .toString();</pre> which produces the string <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. JSONStringer adds them for
- * you. Objects and arrays can be nested up to 20 levels deep.
- * <p>
- * This can sometimes be easier than using a JSONObject to build a string.
