/*
    This script contains teh main functions to rorate ads (logos) on brad pages
    It is included in the logo.ascx and logoStrip.ascx files
    
    Two methods are available
    
    1) "UP" rotation between "places" i.e. available ads move between spots on a page (used on title classification pages)

    2) "ACROSS" rotation within a place, which keeps items distinct to a location i.e. intellagencia home page, has 5 logos, 3 might be static (single items) the others rotate
        The term across comes from the recordset grouping, to imagine the extra rows wiating off the side (for a given spot)
