Sorts files by date and puts them in subdirectories by year and month

This project was designed to sort photos (mainly .JPG files) by year and month. It takes a source directory where a bunch of photos are mixed together and copies the photos in that directory to a series of folders in the destination directory named by year and month under year.

If you want to sort more than JPG files there is an if statement in the only for loop that can be changed to include more file types or not to restrict any file types at all.
