Bonus Tutorial: Using generators to return result bodies

Instead of returning a complete result string, you can use the yield
statement to return one result part after another. This may be convenient
in situations where using a template package like CherryPy or Cheetah
would be overkill, and messy string concatenation too uncool. ;-)
