Minor grammatical/documentation improvement

Hi,
I'd like to suggest that the documentation for the Collections API be updated to reflected what I've found to be the correct spelling on "compliment" in the section on Sets. Here is the page link: http://groovy.codehaus.org/JN1015-Collections

A compliment is a positive remark: http://www.merriam-webster.com/dictionary/compliment

I believe it would be more correct to use the work complement:
http://www.merriam-webster.com/dictionary/complement

For example, for the set of integers 1..10, the complement of the set [1,2,4,6,8,10] would be [3,5,7,8,9]. This is a minor issue but is more correct from a usage point of view.

Thanks!
