// 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.
