* AccessKey Hints
*
* Checks all HTML elements on this page that can have an accesskey attribute
* (<a>, <area>, <button>, <input>, <label>, <legend> and <textarea>)
* and creates or appends the title attribute to include platform-specific
* hint in the title, i.e. "Alt+S" (Win)
* or "Ctrl+S)" (Mac). If a title exists, a space plus the hint wrapped in
* parentheses is appended. The only exception is if the title already contains
* 'accesskey', 'Alt+' or 'Ctrl+' (case-insensitive) in which case this script
* will leave it alone.
*
* Use the following markup to include the library:
* <script type="text/javascript" src="access-key-hints.js"></script>

* 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".

// 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.
