Copyrighter

Handy way to print out copyright dates, like in a footer.

The following examples assume it's 2012

© 2012
=> "2012"

This will automatically change to "2012 – 2013" next year!

# © will take an integer
© 1999
=> "1999 – 2012"
# or a range
© 1492..1566
=> "1492 – 1566"

You can also provide an optional second argument, which will be used to join the string

© 1999, " to "
=> "1999 to 2012"
