+// 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.

+// - partialChars - How many characters to enter before triggering
