v0.7.0

Rewritten codebase without vulnerable vorpal #57

Thanks to @AndreMaz, he has rewritten the REPL module because we had a lot of issue with the unmaintained vorpal dependency.
This new version is compatible with the previous versions and support everything what supported in previous versions but it can open new opportunities for us in the future.

Kudos to André 🎉

You may encounter changes in operations, this is why we increased the major version number.
