  #
  #     Netzke::Core.setup do |config|
  #       config.ext_location = "/home/netzke/ext-3.3.0"
  #       config.icons_uri = "/images/famfamfam/icons"
  #       # ...
  #     end
  #
  # The following configuration options are available:
  # * ext_location - absolute path to your Ext code root
  # * icons_uri - relative URI to the icons
