 /* 
	Script by: Tim Wheeler http://tjwheeler.blogspot.com/
	This script retrieves the classification properties from the Root Web of the current site collection's property bag.
	It then injects html positioned at the top center of the page identifying the content classification.
	If the properties are not present or invalid it will show an Unclassified name.
	This script should be referenced in the master page: Eg;
	<SharePoint:ScriptLink language="javascript" name="~SiteCollection/style library/classify/classify.js" OnDemand="false" runat="server" Localizable="false" /> 
	Thanks to Jeremy Thake for his post on retrieving the property bag values: http://www.jeremythake.com/2013/10/using-the-sharepoint-csom-api-to-get-a-property-bag-value/
