 /**
  * Initialises the CSS classes that will be added to body tag of the page.
  *
  * The function is responsible for adding all of the critical CSS classes
  * that describe the current page, and its state.
  * This includes classes that describe the following for example:
  *    - Current language
  *    - Language direction
  *    - YUI CSS initialisation
  *    - Pagelayout
  * These are commonly used in CSS to target specific types of pages.
