// 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.

 * MZOverlay
 * 
 * Moves the element with the given id (contentId) into an overlay and shows the whole thing.
 * After closing the overlay, the element is moved back to its old position.
 * 
 * CSS styles are not included in this script! You have to set it manually (so there is a 
 * strict breakup between different programming languages and the styles are set for the whole system 
 * in one css line (and not in the overlay itself or in each javascript call of the overlay *grusel*)
 * 
 * Example:
 * #mzoverlay-content{ background: #fff; max-width: 950px; z-index: 10002; border: 1px solid #ccc; padding: 20px; text-align: left; }
 * #mzoverlay-content .close{ width: 17px; height: 17px; position: absolute; top: 10px; right: 10px; background: url("../images/i_icons.gif") no-repeat left -208px; cursor: pointer; }
 * #mzoverlay{ background: #fff; z-index: 10001; width: 100%; height: 100%; top: 0; left: 0; }
 * #mzoverlay-loading{ width: 300px; height: 200px; background: url("../images/loading.gif") no-repeat center center;  }
 * a.mzoverlay-open{ cursor: pointer; }
 * #mzoverlay-custom-loading{ width: 100%; height: 100%; position: absolute; top: 0; left: 0; background: #fff url("../images/loading.gif") no-repeat center center; -ms-filter:"progid:DXImageTransform.Microsoft.Alpha(Opacity=80)"; -moz-opacity:0.8; opacity:0.8; filter:alpha(opacity = 80); z-index: 100;}
 * 
 * Usage of the script:
 * ------------------------------------------
 * <div id="myid" style="display: none; width: 400px;">
 *  *** your content ***
 * </div>
 * <a class="mzoverlay-open" onclick="mzoverlay.open('myid', {'modal':true})">Open mzoverlay</a>
 * ------------------------------------------
 * 
 * You can also define a non existing id -> the element will be created automatically in the overlay div
 * for easily use with ajax - automatically a loading wheel will be shown!
 * if you got your data from the ajax request, use mzoverlay.updateContent('data') for updating the content
 * with autoresizing ;-)
 * 
 * if you do some ajax request with an opened overlay, you can use the methods 
 * mzoverlay.showLoadingWheel() or mzoverlay.hideLoadingWheel() 
 * for the loading wheel
