// Autocompleter.Base handles all the autocompletion functionality
// that's independent of the data source for autocompletion. This
// includes drawing the autocompletion menu, observing keyboard
// and mouse events, and similar.
//
// Specific autocompleters need to provide, at the very least,
// 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.

   * @fileoverview
   * Beauty Tips is a jQuery tooltips plugin which uses the canvas drawing element
   * in the HTML5 spec in order to dynamically draw tooltip "talk bubbles" around

   * similar to Google Maps which both provides similar talk-bubbles and uses the
   * canvas element to draw them.
   *
   * The canvas element is supported in modern versions of FireFox, Safari, and
   * Opera. However, Internet Explorer needs a separate library called ExplorerCanvas
   * included on the page in order to support canvas drawing functions. ExplorerCanvas
   * was created by Google for use with their web apps and you can find it here:
   * http://excanvas.sourceforge.net/
   *
   * Beauty Tips was written to be simple to use and pretty. All of its options
   * are documented at the bottom of this file and defaults can be overwritten
   * globally for the entire page, or individually on each call.
   *
   * By default each tooltip will be positioned on the side of the target element
   * which has the most free space. This is affected by the scroll position and
   * size of the current window, so each Beauty Tip is redrawn each time it is
   * displayed. It may appear above an element at the bottom of the page, but when
   * the page is scrolled down (and the element is at the top of the page) it will
   * then appear below it. Additionally, positions can be forced or a preferred
   * order can be defined. See examples below.
   *
   * To fix z-index problems in IE6, include the bgiframe plugin on your page
   * http://plugins.jquery.com/project/bgiframe - BeautyTips will automatically
   * recognize it and use it.
   *
   * BeautyTips also works with the hoverIntent plugin
   * http://cherne.net/brian/resources/jquery.hoverIntent.html
   * see hoverIntent example below for usage
   *
   * Usage
   * The function can be called in a number of ways.
   * $(selector).bt();
   * $(selector).bt('Content text');
   * $(selector).bt('Content text', {option1: value, option2: value});
   * $(selector).bt({option1: value, option2: value});
   *
   * For more/better documentation and lots of examples, visit the demo page included with the distribution
