MultipartUpload uses an operation queue to chunk up and upload all pieces of a large file to S3. It does not handle persistence so if you only get part way through an upload, you have to manage the process of re-uploading again.

Usage
See example application.
Create and retain an instance by passing your S3 credentials:
[self setUploader:[[[MultiPartFileUploader alloc] initWithS3Key:kS3AccessKey secret:kS3SecretKey bucket:kS3Bucket] autorelease]];
Create and retain an operation queue that can be used to do the individual part uploads:
[self setQueue:[[[NSOperationQueue alloc] init] autorelease]];
Pass a the URL for a locally-stored file to the uploader. Optionally set a delegate for progress updates.
[[self uploader] uploadFileAtUrl:url operationQueue:[self queue] delegate:self];
