Download and combine OverDrive.com audiobooks into a single m4b file without transcoding.

Useage:

OverdriveDownloader "path\to\odmfile.odm"

OverdriveDownloader will acquire a license and save it to the ODM file for future use. Then it downloads all mp3 parts to the odm file's directory (or loads the mp3s if they've already downloaded). It then merges all mp3 parts into a single m4b file, complete with metadata tags and chapter markers.
