Franco,

Sorry about the previous pull request. I was new to github, and thought I was updating your repo into mine. Anyhow, I do have some changes here. Basically what I wanted to do before, have BagIt.new() (now BagIt.create()) not actually create any files or directories.

THIS CHANGE WILL BREAK PEOPLE'S CODE.

However, the fix is easy - Wherever they have BagIt.new(), they'll have to change it to BagIt.create!()

lemme know if you have any concerns/questions.
