it works like this (just copy and paste)

      end

      def self.foo
        puts("Hello from foo")
      end
  end

  def self.generate_new_class(name)#, parent = Class)
    const_set(name, Class.new(Normal))
  end
end

ClassGenerator.generate_new_class(:MyNew)

ClassGenerator::MyNew.foo
ClassGenerator::MyNew.add_method( 'bar', "Hello from Bar")
s = ClassGenerator::MyNew.new
puts(s.bar)
ClassGenerator::MyNew.add_index('write',1)
ClassGenerator::MyNew.add_index('read',2)
ClassGenerator::MyNew.add_index('create',3)
puts( 'Write: '+s.write.to_s)
puts( 'Read: '+s.read.to_s)
puts( 'Create: '+s.create.to_s)
puts( '1: '+s.s_1)
puts( '2: '+s.s_2)
puts( '3: '+s.s_3)
