/**
	* Class ContentBlockController - selects and renders items in a content block.
	*
	* This is the View class for display functionality of the ContentBlock class.
	*  It provides a div based area for content with hierarchy, css id and class
	* and a relationship to the basic areas provided by PageController. It is to a
	* ContentBlock that a ContentItem, MenuItem or ActionItem is assigned. This
	* class will render any child ContentBlocks and all associated Items. These
	* associations may configured via the QuintaCMS administrative interface and
	* will then automatically be reflected in the associated PageController display.
	*
	* This class is created by PageController which passes a reference to the main parent
	* object and the ContentBlock object from the content_block table in the database.
