NAME:
	Popup

DESCRIPTION:
	Provides functionality to open pop-up windows and set up
	linkages to allow objects to open popup windows when clicked

USAGE:
	Place the XHTML shown in the example on the page and make a call to the object

		YAHOO.Muscle.popupwin.init();

	The XHTML must be marked up with the following class definitions
		Add 'popupOpener' class to an object, along with a known window sizing class (if required)

NOTES:
	Normally associated with a link/anchor, but has "step-up" ability - for example, an image tag within
	an anchor will cause the click-through to return the img tag as the calling object - and we obviously
	need the anchor.

EXAMPLES :

	<a href="/toolsanddownloads/dietplan1500cals.html" class="popupOpener bigWindow">
		Click here to open a big window!
	</a>

	<a href="/toolsanddownloads/dietplan1500cals.html" class="popupOpener">
		This link has no sizing class and will default to medium when clicked
	</a>
