This library works fine on Lion (and even compiles fine for 10.6 too, but haven't had a chance to actually test) and would appreciate the target being set lower. Potentially closes #83 unless we should just bump it down all the way to 10.6.
decrement deployment target
Thanks for the PR @natevw. Sorry for taking so long to get back to you on this, but it looks good to me! Merging.
