Script: TipsX3.js
	Tooltips, BubbleTips, whatever they are, they will appear on mouseover

License:

Credits:
	The idea behind Tips.js is based on Bubble Tooltips (<http://web-graphics.com/mtarchive/001717.php>) by Alessandro Fulcitiniti <http://web-graphics.com>
	TipsX3.js is based on Tips.js, with slight modifications, by razvan@e-magine.ro
*/

/*
Class: TipsX3
	Display a tip on any element with a title and/or href.

Note:
	Tips requires an XHTML doctype.

Arguments:
	elements - a collection of elements to apply the tooltips to on mouseover.
	options - an object. See options Below.

Options:
	maxTitleChars - the maximum number of characters to display in the title of the tip. defaults to 30.

	onShow - optionally you can alter the default onShow behaviour with this option (like displaying a fade in effect);
	onHide - optionally you can alter the default onHide behaviour with this option (like displaying a fade out effect);

	showDelay - the delay the onShow method is called. (defaults to 100 ms)
	hideDelay - the delay the onHide method is called. (defaults to 100 ms)

	className - the prefix for your tooltip classNames. defaults to 'tool'.

		the whole tooltip will have as classname: tool-tip

		the title will have as classname: tool-title

		the text will have as classname: tool-text

	offsets - the distance of your tooltip from the mouse. an Object with x/y properties.
	fixed - if set to true, the toolTip will not follow the mouse.
	
	loadingText - text to display as a title while loading an AJAX tooltip.
	
	errTitle, errText - text to display when there's a problem with the AJAX request.

Example:
	(start code)
	<img src="/images/i.png" title="The body of the tooltip is stored in the title" class="toolTipImg"/>
	<script>
		var myTips = new Tips($$('.toolTipImg'), {
			maxTitleChars: 50	//I like my captions a little long
		});
	</script>
	(end)

Note:
	The title of the element will always be used as the tooltip body. If you put :: on your title, the text before :: will become the tooltip title.
	If you put DOM:someElementID in your title, $('someElementID').innerHTML will be used as your tooltip contents (same syntax as above).
	If you put AJAX:http://www.example.com/path/to/ajax_file.php in your title, the response text will be used as tooltip contents (same syntax as above). Either absolute or relative paths are ok.
