ABC

[JSAbrahams]

Relevant issues

• Partially fixes #331

Summary

• Group from imports together
• Specify @abstractmethod
• Specify ABC class if abstract. However, also added to classes which already have a parent which is abstract. This redundancy can be fixed in the next PR.

However, generate stage does not use a Context to check whether an abstract class already had a parent which is abstract. This results in redundant ABC parents. This should be also fixed (in a separate PR) before closing #331.

Added Tests

• Update some test to check that ABC and @abstractmethod imported and used.
• Concrete method in abstract class (interface)
