class parent
  @selectors = {
    'a':  'hello',
    'b':  'world',
  }
end

class child < parent
  @selectors = {
    'b':  'foo',
    'c':  'bar',
  }

  def initialize()
    what I want here is to merge the selectors from my child class and my parent class.  So puts(@selectors) would show :
    {a:hello,b:foo,c:bar}
  }

end
