Notes

Inspired by two projects:

• https://github.com/aroth/react-native-uploader
• https://github.com/tj/node-s3-policy

... with noteable enhancements:

• support AWS Signature Version 4: AWS4-HMAC-SHA256
• support for files from the assets library, base64 data: or file: paths
• no external dependencies (ie: AFNetworking)

... and limitations:

• support for one file at a time
