Focus:

• [x] Strip the core to basic functionality
• [x] Do not require inline JavaScript (CSP)
• [x] Provide Starters based on usages (dataStarter, mutationStarter)
• [x] Provide lazy function to lazy load components scripts
• [ ] Remove services / provide services component?

Seems like it was a bad idea to use codesandbox to create the prototype as it seems remove the content of all js files 🙈
