Updating CHANGES and VERSION.
Doc tweak.
Remove references to line numbers in tutorial text

Removed line numbers in the text because it was difficult to keep these
up-to-date.  Changed some wording and moved sample scripts before (rather
than after) the descriptive text in order to keep it easy to understand.
