[PGCanada] Public Domain Wizard (beta)

[Wallace J.McLean]

I have developed a Public Domain Wizard, in the form of an Excel 
spreadsheet, which should (if it works) be able to tell you whether a 
given book is copyrighted or public domain in Canada.

(There's one grey area it will warn you about if you encounter it, and 
one hellishly difficult sub-area of pre-1924 copyright law which I 
chose to ignore.)

Would anyone like to test-drive?
