-// 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.

-//
-// 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
