# provides a slick way to add classes inside haml attribute collections
# 
# examples:
#   %div{add_class("current")} 
#   #=> adds the "current" class to the div
#   
#   %div{add_class("current", :if => current?)} 
#   #=> adds the "current" class to the div if current? method 
#
#   %div{add_class("highlight", :unless => logged_in?)}
