// a getUpdatedChoices function that will be invoked every time
// the text inside the monitored textbox changes. This method
// should get the text for which to provide autocompletion by
// invoking this.getToken(), NOT by directly accessing
// this.element.value. This is to allow incremental tokenized
// autocompletion. Specific auto-completion logic (AJAX, etc)
// belongs in getUpdatedChoices.
//
// Tokenized incremental autocompletion is enabled automatically
// when an autocompleter is instantiated with the 'tokens' option
// in the options parameter, e.g.:
// new Ajax.Autocompleter('id','upd', '/url/', { tokens: ',' });
// will incrementally autocomplete with a comma as the token.
// Additionally, ',' in the above example can be replaced with
// a token array, e.g. { tokens: [',', '\n'] } which
// enables autocompletion on multiple tokens. This is most
// useful when one of the tokens is \n (a newline), as it
// allows smart autocompletion after linebreaks.

// The local array autocompleter. Used when you'd prefer to
// inject an array of autocompletion options into the page, rather
// than sending out Ajax queries, which can be quite slow sometimes.
//
// The constructor takes four parameters. The first two are, as usual,
// the id of the monitored textbox, and id of the autocompletion menu.
// The third is the array you want to autocomplete from, and the fourth
// is the options block.
//
// Extra local autocompletion options:
// - choices - How many autocompletion choices to offer
//
// - partialSearch - If false, the autocompleter will match entered
//                    text only at the beginning of strings in the
//                    autocomplete array. Defaults to true, which will
//                    match text at the beginning of any *word* in the
//                    strings in the autocomplete array. If you want to
//                    search anywhere in the string, additionally set
//                    the option fullSearch to true (default: off).
//
// - fullSsearch - Search anywhere in autocomplete array strings.
//
// - partialChars - How many characters to enter before triggering
//                   a partial match (unlike minChars, which defines
//                   how many characters are required to do any match
//                   at all). Defaults to 2.
//
// - ignoreCase - Whether to ignore case when autocompleting.
//                 Defaults to true.
//
// It's possible to pass in a custom function as the 'selector'
// option, if you prefer to write your own autocompletion logic.
// In that case, the other options above will not apply unless
// you support them.

 * Since devices may use either touch or mouse or both, there is no way to
 * know the user's preferred pointer type until they interact with the site.
 *
 * To accommodate this, this class provides a method and two events
 * to determine the user's preferred pointer type.
 *
 * - getPointer() returns the last used pointer type, or, if the user has
 *   not yet interacted with the site, falls back to a Modernizr test.
 *
 * - The mouse-detected event is triggered on the window object when the user
 *   is using a mouse pointer input, or has switched from touch to mouse input.
 *   It can be observed in this manner: $j(window).on('mouse-detected', function(event) { // custom code });
 *
 * - The touch-detected event is triggered on the window object when the user
 *   is using touch pointer input, or has switched from mouse to touch input.
 *   It can be observed in this manner: $j(window).on('touch-detected', function(event) { // custom code });

    // This plugin requires a specific markup structure. The plugin expects a set of elements that it
    // will use as the toggle link. It then hides all immediately following siblings and toggles the sibling's
    // visibility when the toggle link is clicked.
    //
    // Example markup:
    // <div class="block">
    //     <div class="block-title">Trigger</div>
    //     <div class="block-content">Content that should show when </div>
    // </div>

    //     destruct: defaults to false, but if true, the plugin will remove itself, display content, and remove event handlers
