/*
  Advertisement Metadata 
 
  Section default is NEWS.
  This file will produce a SITE and AREA tag for the current page based
  on the parameters sent through from baseAd within initPost. 

  siteLookup: 
    This object houses valid site values.
    A site has to exist in this object to be valid else the default 
    site specified in siteAdvertDesc.site will be used
    Each entry contains an object which can have two properties:
      site: The value here will over-ride the site passed in.
        i.e: 
         - 'BRISBANETIMES': {site: 'BRISTIMES'},
            BRISBANETIMES becomes BRISTIMES
      cat:
        i.e: 
         - 'RUGBYHEAVEN': {cat: "SPORT"},
            RUGBYHEAVEN always has section SPORT irrespective of the cat property
            set in baseAd.
         - If a cat value is set here it is given precedence over any value in 
            catSectionLookup (below)
  
  catSectionLookup:
    This object houses valid cat -> section conversions.
    A cat has to exist in this table to be valid else NEWS will be used. 
      i.e:
       - An ad's section with cat TECHNOLOGY or DLHOME becomes TECH
       - An ad's section with cat SPORT stays as SPORT.
       - An ad's section with cat AAA becomes NEWS.
    
  areaExtend: 
    This object houses sections' AREAs to extend with further properties.
      i.e:
       - 'BUSINESS': ['cat2', 'cat3']
        All business sections will have cat2 and cat3 appended to their AREA tag.
