	/**
	* PageController - handles the content block placement for a single page in Quinta.
	* 
	* This class is the manager for placing content blocks associated with a Page.
	* It sets up the ContentBlocks according to some default areas as defined in the
	* block_location_type table in the database, These are currently hard coded to offer
	* a default generic layout with a header, two side bars, a center content area and
	* a footer. Extra divs are also provided for extra flexibility. All divs loaded by this
	* class are contained within the master container div (see the template).
	*
	* You can modify the default layout via the style sheet associated with each Page
	* - the style sheet to use for a page can be set via the Quinta CMS administrative interface.
	* It is also not difficult to change the default areas - simply edit the template and ensure
	* that the associated div CSS id names are in the block_location_type table and then
	* you can associate ContentBlocks with those areas (again through the admin interface).
	*
	*NOTE: One course of development would be to subclass this for page types. This
	* is already in the database, but it is not used yet - an architectural decision to be made ...
