/**
    * Class ContentBlockView - 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 PageView. 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 QuasiCMS administrative interface and
    * will then automatically be reflected in the associated PageView display.
    *
    * This class is created by PageView which passes a reference to the main parent
    * object and the ContentBlock object from the content_block table in the database.
