- [ ] Minor fixes
 - [X] Remove 'get' prefix in methods
 - [ ] Add pkg.go file
 - [ ] Rename `Get` method to `Metadata`
- [ ] Testing
 - [ ] Add `v1` directory to Acceptance Tests
 - [ ] Break-up storage_test.go into multiple files
 - [ ] Add Unit Tests
 - [ ] Improve Acceptance Tests (right now they assume an empty object store)
- [ ] Additions
 - [ ] Chunked download / upload
 - [ ] Improve documentation
 - [ ] Return more informative errors
 - [ ] Implement new Pager
