Initial Version after the refactor. Changes:
- mp3Data has been moved to the Navarr namespace.
- Instead of returning false for errors, mp3Data now throws exceptions. (For file not found and failure to analyze)
- We've added tests. For this release we're at 83% Code Coverage!
- Moved to composer for managing our getid3 dependency (instead of including it in our codebse)
- Added export-ignore .gitattributes so you don't clutter your vendor directory with unnecessary files.
