Implement CI

[hectoritr]

We need to implement a Continuous Integration platform into this repo to do the following tasks automatically when a new change to master is made.

• Run automated testing (when ready).
• Update Github repository with the latest release information.
• Publish to web.
• Build Android bundle.
• Build iOS package.
