    /* API for adding a hook, created by David Pritchard
       https://github.com/daveagp
  
      [this documentation is a bit deprecated since Philip made try_hook a
       method of ExecutionVisualizer, but the general ideas remain]
  
     An external user should call
       add_pytutor_hook("hook_name_here", function(args) {...})
     args will be a javascript object with several named properties;
     this is meant to be similar to Python's keyword arguments.
  
     The hooked function should return an array whose first element is a boolean:
     true if it completely handled the situation (no further hooks
     nor the base function should be called); false otherwise (wasn't handled).
     If the hook semantically represents a function that returns something,
     the second value of the returned array is that semantic return value.
  
     E.g. for the Java visualizer a simplified version of a hook we use is:
  
    add_pytutor_hook(
      "isPrimitiveType",
      function(args) {
        var obj = args.obj; // unpack
        if (obj instanceof Array && obj[0] == "CHAR-LITERAL")
          return [true, true]; // yes we handled it, yes it's primitive
        return [false]; // didn't handle it, let someone else
      });
  
     Hook callbacks can return false or undefined (i.e. no return
     value) in lieu of [false].
  
     NB: If multiple functions are added to a hook, the oldest goes first. */

// About: Support and Testing
// 
// Information about what version or versions of jQuery this plugin has been
// tested with, what browsers it has been tested in, and where the unit tests
// reside (so you can test it yourself).
// 
// jQuery Versions - 1.2.6, 1.3.2, 1.4.1, 1.4.2
// Browsers Tested - Internet Explorer 6-8, Firefox 2-4, Chrome 5-6, Safari 3.2-5,
//                   Opera 9.6-10.60, iPhone 3.1, Android 1.6-2.2, BlackBerry 4.6-5.
// Unit Tests      - http://benalman.com/code/projects/jquery-bbq/unit/
// 
// About: Release History
// 
// 1.3pre - (8/26/2010) Integrated <jQuery hashchange event> v1.3, which adds
//         document.title and document.domain support in IE6/7, BlackBerry
//         support, better Iframe hiding for accessibility reasons, and the new
//         <jQuery.fn.hashchange> "shortcut" method. Added the
//         <jQuery.param.sorted> method which reduces the possibility of
//         extraneous hashchange event triggering. Added the
//         <jQuery.param.fragment.ajaxCrawlable> method which can be used to
//         enable Google "AJAX Crawlable mode."
// 1.2.1 - (2/17/2010) Actually fixed the stale window.location Safari bug from
//         <jQuery hashchange event> in BBQ, which was the main reason for the
//         previous release!
// 1.2   - (2/16/2010) Integrated <jQuery hashchange event> v1.2, which fixes a
//         Safari bug, the event can now be bound before DOM ready, and IE6/7
//         page should no longer scroll when the event is first bound. Also
//         added the <jQuery.param.fragment.noEscape> method, and reworked the
//         <hashchange event (BBQ)> internal "add" method to be compatible with
//         changes made to the jQuery 1.4.2 special events API.
// 1.1.1 - (1/22/2010) Integrated <jQuery hashchange event> v1.1, which fixes an
//         obscure IE8 EmulateIE7 meta tag compatibility mode bug.
// 1.1   - (1/9/2010) Broke out the jQuery BBQ event.special <hashchange event>
//         functionality into a separate plugin for users who want just the
//         basic event & back button support, without all the extra awesomeness
//         that BBQ provides. This plugin will be included as part of jQuery BBQ,
//         but also be available separately. See <jQuery hashchange event>
//         plugin for more information. Also added the <jQuery.bbq.removeState>
//         method and added additional <jQuery.deparam> examples.
// 1.0.3 - (12/2/2009) Fixed an issue in IE 6 where location.search and
//         location.hash would report incorrectly if the hash contained the ?
//         character. Also <jQuery.param.querystring> and <jQuery.param.fragment>

// 1.0.2 - (10/10/2009) Fixed an issue in IE 6/7 where the hidden IFRAME caused
//         a "This page contains both secure and nonsecure items." warning when
//         used on an https:// page.
// 1.0.1 - (10/7/2009) Fixed an issue in IE 8. Since both "IE7" and "IE8
//         Compatibility View" modes erroneously report that the browser
//         supports the native window.onhashchange event, a slightly more
//         robust test needed to be added.

  // Event: hashchange event (BBQ)
  // 
  // Usage in jQuery 1.4 and newer:
  // 
  // In jQuery 1.4 and newer, the event object passed into any hashchange event
  // callback is augmented with a copy of the location.hash fragment at the time
  // the event was triggered as its event.fragment property. In addition, the
  // event.getState method operates on this property (instead of location.hash)
  // which allows this fragment-as-a-state to be referenced later, even after
  // window.location may have changed.
  // 
  // Note that event.fragment and event.getState are not defined according to
  // W3C (or any other) specification, but will still be available whether or
  // not the hashchange event exists natively in the browser, because of the
  // utility they provide.
  // 
  // The event.fragment property contains the output of <jQuery.param.fragment>
  // and the event.getState method is equivalent to the <jQuery.bbq.getState>
  // method.
  // 
  // > $(window).bind( 'hashchange', function( event ) {
  // >   var hash_str = event.fragment,
  // >     param_obj = event.getState(),
  // >     param_val = event.getState( 'param_name' ),
  // >     param_val_coerced = event.getState( 'param_name', true );
  // >   ...
  // > });
  // 
  // Usage in jQuery 1.3.2:
  // 
  // In jQuery 1.3.2, the event object cannot to be augmented as in jQuery 1.4+,
  // so the fragment state isn't bound to the event object and must instead be
  // parsed using the <jQuery.param.fragment> and <jQuery.bbq.getState> methods.
  // 
  // > $(window).bind( 'hashchange', function( event ) {
  // >   var hash_str = $.param.fragment(),
  // >     param_obj = $.bbq.getState(),
  // >     param_val = $.bbq.getState( 'param_name' ),
  // >     param_val_coerced = $.bbq.getState( 'param_name', true );
  // >   ...
  // > });
  // 
  // Additional Notes:
  // 
  // * Due to changes in the special events API, jQuery BBQ v1.2 or newer is
  //   required to enable the augmented event object in jQuery 1.4.2 and newer.
  // * See <jQuery hashchange event> for more detailed information.

// About: Support and Testing
// 
// Information about what version or versions of jQuery this plugin has been
// tested with, what browsers it has been tested in, and where the unit tests
// reside (so you can test it yourself).
// 
// jQuery Versions - 1.2.6, 1.3.2, 1.4.1, 1.4.2
// Browsers Tested - Internet Explorer 6-8, Firefox 2-4, Chrome 5-6, Safari 3.2-5,
//                   Opera 9.6-10.60, iPhone 3.1, Android 1.6-2.2, BlackBerry 4.6-5.
// Unit Tests      - http://benalman.com/code/projects/jquery-hashchange/unit/
// 
// About: Known issues
// 
// While this jQuery hashchange event implementation is quite stable and
// robust, there are a few unfortunate browser bugs surrounding expected
// hashchange event-based behaviors, independent of any JavaScript
// window.onhashchange abstraction. See the following examples for more
// information:
// 
// Chrome: Back Button - http://benalman.com/code/projects/jquery-hashchange/examples/bug-chrome-back-button/
// Firefox: Remote XMLHttpRequest - http://benalman.com/code/projects/jquery-hashchange/examples/bug-firefox-remote-xhr/
// WebKit: Back Button in an Iframe - http://benalman.com/code/projects/jquery-hashchange/examples/bug-webkit-hash-iframe/
// Safari: Back Button from a different domain - http://benalman.com/code/projects/jquery-hashchange/examples/bug-safari-back-from-diff-domain/
// 
// Also note that should a browser natively support the window.onhashchange 
// event, but not report that it does, the fallback polling loop will be used.
// 
// About: Release History
// 
// 1.3   - (7/21/2010) Reorganized IE6/7 Iframe code to make it more
//         "removable" for mobile-only development. Added IE6/7 document.title
//         support. Attempted to make Iframe as hidden as possible by using
//         techniques from http://www.paciellogroup.com/blog/?p=604. Added 
//         support for the "shortcut" format $(window).hashchange( fn ) and
//         $(window).hashchange() like jQuery provides for built-in events.
//         Renamed jQuery.hashchangeDelay to <jQuery.fn.hashchange.delay> and
//         lowered its default value to 50. Added <jQuery.fn.hashchange.domain>
//         and <jQuery.fn.hashchange.src> properties plus document-domain.html
//         file to address access denied issues when setting document.domain in
//         IE6/7.
// 1.2   - (2/11/2010) Fixed a bug where coming back to a page using this plugin
//         from a page on another domain would cause an error in Safari 4. Also,
//         IE6/7 Iframe is now inserted after the body (this actually works),
//         which prevents the page from scrolling when the event is first bound.
//         Event can also now be bound before DOM ready, but it won't be usable
//         before then in IE6/7.
// 1.1   - (1/21/2010) Incorporated document.documentMode test to fix IE8 bug
//         where browser version is incorrectly reported as 8.0, despite
//         inclusion of the X-UA-Compatible IE=EmulateIE7 meta tag.
// 1.0   - (1/9/2010) Initial Release. Broke out the jQuery BBQ event.special
//         window.onhashchange functionality into a separate plugin for users
//         who want just the basic event & back button support, without all the
//         extra awesomeness that BBQ provides. This plugin will be included as
//         part of jQuery BBQ, but also be available separately.

  // 
  // Bind a handler to the window.onhashchange event or trigger all bound
  // window.onhashchange event handlers. This behavior is consistent with
  // jQuery's built-in event handlers.
  // 
  // Usage:
  // 
  // > jQuery(window).hashchange( [ handler ] );
  // 
  // Arguments:
  // 
  //  handler - (Function) Optional handler to be bound to the hashchange
  //    event. This is a "shortcut" for the more verbose form:
  //    jQuery(window).bind( 'hashchange', handler ). If handler is omitted,
  //    all bound window.onhashchange event handlers will be triggered. This
  //    is a shortcut for the more verbose
  //    jQuery(window).trigger( 'hashchange' ). These forms are described in
  //    the <hashchange event> section.
  // 
  // Returns:
  // 
  //  (jQuery) The initial jQuery collection of elements.
  
  // Allow the "shortcut" format $(elem).hashchange( fn ) for binding and
  // $(elem).hashchange() for triggering, like jQuery does for built-in events.

  // Property: jQuery.fn.hashchange.delay
  // 
  // The numeric interval (in milliseconds) at which the <hashchange event>
  // polling loop executes. Defaults to 50.
  
  // Property: jQuery.fn.hashchange.domain
  // 
  // If you're setting document.domain in your JavaScript, and you want hash
  // history to work in IE6/7, not only must this property be set, but you must
  // also set document.domain BEFORE jQuery is loaded into the page. This
  // property is only applicable if you are supporting IE6/7 (or IE8 operating
  // in "IE7 compatibility" mode).
  // 
  // In addition, the <jQuery.fn.hashchange.src> property must be set to the
  // path of the included "document-domain.html" file, which can be renamed or
  // modified if necessary (note that the document.domain specified must be the
  // same in both your main JavaScript as well as in this file).
  // 
  // Usage:
  // 
  // jQuery.fn.hashchange.domain = document.domain;
  
  // Property: jQuery.fn.hashchange.src
  // 
  // If, for some reason, you need to specify an Iframe src file (for example,
  // when setting document.domain as in <jQuery.fn.hashchange.domain>), you can
  // do so using this property. Note that when using this property, history
  // won't be recorded in IE6/7 until the Iframe src file loads. This property
  // is only applicable if you are supporting IE6/7 (or IE8 operating in "IE7
  // compatibility" mode).
  // 
  // Usage:
  // 
  // jQuery.fn.hashchange.src = 'path/to/file.html';

  // Event: hashchange event
  // 
  // Fired when location.hash changes. In browsers that support it, the native
  // HTML5 window.onhashchange event is used, otherwise a polling loop is
  // initialized, running every <jQuery.fn.hashchange.delay> milliseconds to
  // see if the hash has changed. In IE6/7 (and IE8 operating in "IE7
  // compatibility" mode), a hidden Iframe is created to allow the back button
  // and hash-based history to work.
  // 
  // Usage as described in <jQuery.fn.hashchange>:
  // 
  // > // Bind an event handler.
  // > jQuery(window).hashchange( function(e) {
  // >   var hash = location.hash;
  // >   ...
  // > });
  // > 
  // > // Manually trigger the event handler.
  // > jQuery(window).hashchange();
  // 
  // A more verbose usage that allows for event namespacing:
  // 
  // > // Bind an event handler.
  // > jQuery(window).bind( 'hashchange', function(e) {
  // >   var hash = location.hash;
  // >   ...
  // > });
  // > 
  // > // Manually trigger the event handler.
  // > jQuery(window).trigger( 'hashchange' );
  // 
  // Additional Notes:
  // 
  // * The polling loop and Iframe are not created until at least one handler
  //   is actually bound to the 'hashchange' event.
  // * If you need the bound handler(s) to execute immediately, in cases where
  //   a location.hash exists on page load, via bookmark or page refresh for
  //   example, use jQuery(window).hashchange() or the more verbose 
  //   jQuery(window).trigger( 'hashchange' ).
  // * The event can be bound before DOM ready, but since it won't be usable
  //   before then in IE6/7 (due to the necessary Iframe), recommended usage is
  //   to bind it inside a DOM ready handler.
  
  // Override existing $.event.special.hashchange methods (allowing this plugin
  // to be defined after jQuery BBQ in BBQ's source code).
