    /**
      * Adds AJAX autocomplete functionality to the text input field with the 
      * DOM ID specified by +field_id+.
      *
      * This function expects that the called action returns a HTML <ul> list,
      * or nothing if no entries should be displayed for autocompletion.
      *
      * You'll probably want to turn the browser's built-in autocompletion off,
      * so be sure to include a autocomplete="off" attribute with your text
      * input field.
      *
      * The autocompleter object is assigned to a Javascript variable named <tt>field_id</tt>_auto_completer.
      * This object is useful if you for example want to trigger the auto-complete suggestions through
      * other means than user input (for that specific case, call the <tt>activate</tt> method on that object). 
      * 
      * Required +options+ are:
      * <tt>url</tt>::       URL to call for autocompletion results
      *                       in url_for format.
      * 
      * Addtional +options+ are:
      * <tt>update</tt>::    Specifies the DOM ID of the element whose 
      *                       innerHTML should be updated with the autocomplete
      *                       entries returned by the AJAX request. 
      *                       Defaults to field_id + '_auto_complete'
      * <tt>with</tt>::      A JavaScript expression specifying the
      *                       parameters for the XMLHttpRequest. This defaults
      *                       to 'fieldname=value'.
      * <tt>indicator</tt>:: Specifies the DOM ID of an element which will be
      *                       displayed while autocomplete is running.
      * <tt>tokens</tt>::    A string or an array of strings containing
      *                       separator tokens for tokenized incremental 
      *                       autocompletion. Example: <tt>tokens => ','</tt> would
      *                       allow multiple autocompletion entries, separated
      *                       by commas.
      * <tt>min_chars</tt>:: The minimum number of characters that should be
      *                       in the input field before an Ajax call is made
      *                       to the server.
      * <tt>on_hide</tt>::   A Javascript expression that is called when the
      *                       autocompletion div is hidden. The expression
      *                       should take two variables: element and update.
      *                       Element is a DOM element for the field, update
      *                       is a DOM element for the div from which the
      *                       innerHTML is replaced.
      * <tt>on_show</tt>::   Like on_hide, only now the expression is called
      *                       then the div is shown.
      * <tt>select</tt>::    Pick the class of the element from which the value for 
      *                       insertion should be extracted. If this is not specified,
      *                       the entire element is used.
