// 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.
