• Add timeout to test. Compiled CoffeeScript and whitespace changes
• Add dev dependency on coffee-script
• Updated upload_large_stream to return a stream and let the caller control the piping to it, similar to upload_stream.
• fixes #65 - upload_large using chunk_size is corrupting data - also adds the very useful upload_large_stream function. upload_large tests now verify data integrity.
• Add bower to the photo_album sample project.
