Changes
	v1.1 - added slideTypes functionality

To create a slider box you need a containing element with the class "slider".
Inside that you need an element with class "top" and a containing element with class "content".
Inside "top" goes the title; inside "content" goes the sliding content
If you want the slider closed initially, add "closed" to the slider class
Optionally add type-N to the class where N is the number of the slideType you want (starting at 0)

If you want several sliders but only want one to be open at a time, 
add the class "slider-single-id" to each slider, where "id" is any string [a-zA-Z0-9_-] no spaces

EXAMPLE:
<div class="slider type2 slider-single-leftnav">
	<h4 class="top">TITLE</h4>
	<div class="content">
		text text text text text text 
	</div>
</div>

CSS classes are:
	slider
	slider.open
	slider.closed
	slider.animating
	slider .top
	slider .content
