 // 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.
