[Tutor] SwishE web interface

[Lloyd Kvam]

return marks the end of processing in a function.  control is returned
to the caller.

You have multiple results that could be returned as a list.


	return [r.getproperty('searchdocpath') for r in results]
uses "list comprehensions" to return a list of values.  This is a very
handy addition to the language that makes it extremely easy to write a
simple loop and collect the results into a list.
