// 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.

/**
*  This function "patches" an input field (or other element) to use a calendar
*  widget for date selection.
*
*  The "params" is a single object that can have the following properties:
*
*    prop. name   | description
*  -------------------------------------------------------------------------------------------------
*   inputField    | the ID of an input field to store the date
*   displayArea   | the ID of a DIV or other element to show the date
*   button        | ID of a button or other element that will trigger the calendar
*   eventName     | event that will trigger the calendar, without the "on" prefix (default: "click")
*   ifFormat      | date format that will be stored in the input field
*   daFormat      | the date format that will be used to display the date in displayArea
*   singleClick   | (true/false) wether the calendar is in single click mode or not (default: true)
*   firstDay      | numeric: 0 to 6.  "0" means display Sunday first, "1" means display Monday first, etc.
*   align         | alignment (default: "Br"); if you don't know what's this see the calendar documentation
*   range         | array with 2 elements.  Default: [1900, 2999] -- the range of years available
*   weekNumbers   | (true/false) if it's true (default) the calendar will display week numbers
*   flat          | null or element ID; if not null the calendar will be a flat calendar having the parent with the given ID
*   flatCallback  | function that receives a JS Date object and returns an URL to point the browser to (for flat calendar)
*   disableFunc   | function that receives a JS Date object and should return true if that date has to be disabled in the calendar
*   onSelect      | function that gets called when a date is selected.  You don't _have_ to supply this (the default is generally okay)
*   onClose       | function that gets called when the calendar is closed.  [default]
*   onUpdate      | function that gets called after the date is updated in the input field.  Receives a reference to the calendar.
*   date          | the date that the calendar will be initially displayed to
*   showsTime     | default: false; if true the calendar will include a time selector
*   timeFormat    | the time format; can be "12" or "24", default is "12"
*   electric      | if true (default) then given fields/date areas are updated for each move; otherwise they're updated only on close
*   step          | configures the step of the years in drop-down boxes; default: 2
*   position      | configures the calendar absolute position; default: null
*   cache         | if "true" (but default: "false") it will reuse the same calendar object, where possible
*   showOthers    | if "true" (but default: "false") it will show days from other months too
*
*  None of them is required, they all have default values.  However, if you
*  pass none of "inputField", "displayArea" or "button" you'll get a warning
*  saying "nothing to setup".
