	MaxImage 2.0 (Fullscreen Slideshow for use with jQuery Cycle Plugin)
	--------------------------------------------------------------------
	
	Examples and documentation at: http://www.aaronvanderzwan.com/maximage/2.0/

	NOTES:
	This plugin is intended to simplify the creation of fullscreen 
	background slideshows.  It is intended to be used alongside the 
	jQuery Cycle plugin: 
	http://jquery.malsup.com/cycle/
	
	If you simply need a fullscreen background image, please
	refer to the following document for ways to do this that
	are much more simple:
	http://css-tricks.com/perfect-full-page-background-image/
	
	If you have any questions please contact Aaron Vanderzwan
	at http://www.aaronvanderzwan.com/blog/
	Documentation at:
	http://blog.aaronvanderzwan.com/2012/07/maximage-2-0/
	
	HISTORY:
	MaxImage 2.0 is a project first built as jQuery MaxImage Plugin 
	(http://www.aaronvanderzwan.com/maximage/). Once CSS3 came along, 
	the background-size:cover solved the problem MaxImage
	was intended to solve.  However, fully customizable
	fullscreen slideshows is still fairly complex and I have not
	found any helpers for integrating with the jQuery Cycle Plugin.
	MaxCycle is intended to solve this problem.
