**Description**

This PR was started after today's conversation on IRC, we synced with Hari and Paul to remove translator as a dependency from this component. There were some additional cleanups, moving to PSR-4, updating the readme, making the tests pass, correcting some typos on the tests, adding an autoload.php, creating a factory for the service instantiation and registry initialization and some other minor issues.

**todo**:

- [x] update README.md with new structure
@koriym that's a good question. "Which Interface is missing". You go and go find which interface :+1:  .
