// 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.

 WDR:
 Some new options to the get() method:
 
 urlparams -- a js hash of stuff to be added to the query string. 
    simple example:

    generic.templatefactory.get({
        path: '/templates/edit-address-jsdata.tmpl',
        urlparams: {
            ADDRESS_ID: options.addrid
        }
    }).evaluateCallback({
        ...blah blah... 
    });

    this results in the url 'http://(domain)/templates/edit-address-jsdata.tmpl?ADDRESS_ID=88888'
    (assuming 88888 is the value of "options.addrid")
    
    From there, the perl side is plain old $request->param('ADDRESS_ID') or whatever...
    
 method -- HTTP method to use.  default is "GET", but you can override as "POST" if desired.
 
 NOTE - The default get() params use the "GET" http method and no query string.
 This leverages the browser cache to save the gotten file for subsequent calls.
 Therefore, understand that using the urlparams and method options may bypass
 the browser cache, which may or may not be your intent.

 * in the DOM. It will then attempt to insert one directly after a <DIV id="header"> (If no header
 * is found, the method exits.) All the LI child nodes (previous messages) of the UL are hidden.
 * The text property of each error Hash is then displayed as an LI.
 * This method can also alter the style of the input elements that triggered the error.
 * The tags property in an error hash must be an array that contains a string starting with
 * "field." If the optional formNode parameter is supplied, this form node will be
 * searched for the field, and that field will be passed to the generic.showErrorState method.
