-// 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.

+// 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 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

+//                    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.
