/**
* 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>

* 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 20 levels deep.

* adding or replacing values. The values can be any of these types:
* <code>Boolean</code>, <code>JSONArray</code>, <code>JSONObject</code>,

/**
* <h1>Python output</h1>
* <p>
* When Python produces output from code that has been compiled in with the
* 'single' flag to :func:`compile`, any expression that produces a value (such as
* ``1+1``) is passed to ``sys.displayhook``, which is a callable that can do with
* this value whatever it wants. The default behavior of ``sys.displayhook`` in
* the Python interactive prompt is to print to ``sys.stdout`` the :func:`repr` of
* the value as long as it is not ``None`` (which isn't printed at all). In our
* case, the kernel instantiates as ``sys.displayhook`` an object which has
* similar behavior, but which instead of printing to stdout, broadcasts these
* values as ``pyout`` messages for clients to display appropriately.
* <p>
* IPython's displayhook can handle multiple simultaneous formats depending on its
* configuration. The default pretty-printed repr text is always given with the
* ``data`` entry in this message. Any other formats are provided in the
* ``extra_formats`` list. Frontends are free to display any or all of these
* according to its capabilities. ``extra_formats`` list contains 3-tuples of an ID
* string, a type string, and the data. The ID is unique to the formatter
* implementation that created the data. Frontends will typically ignore the ID
* unless if it has requested a particular formatter. The type string tells the
* frontend how to interpret the data. It is often, but not always a MIME type.
* Frontends should ignore types that it does not understand. The data itself is
* any JSON object and depends on the format. It is often, but not always a string.
* <p>
* Message type: ``pyout``::
* <p>
* <pre><code>
* content = {
* # The counter for this execution is also provided so that clients can
* # display it, since IPython automatically creates variables called _N
* # (for prompt N).
* 'execution_count' : int,
*
* # The data dict contains key/value pairs, where the kids are MIME
* # types and the values are the raw data of the representation in that
* # format. The data dict must minimally contain the ``text/plain``
* # MIME type which is used as a backup representation.
* 'data' : dict,
* }
