Enhance existing repo with improved meta data

[jezumbro]

Objective

Improve the interface to the repository by requiring the document_class and collection_name to be defined in the Meta of the new class

Notes

• Adding document_class to Meta to improve the existing codebase.
• Adding more types and moving the comments to be doc strings associated with the corresponding function
• Refactored existing codebase
• Ran black and isort on existing codebase

Can you include back and isort on development dependencies and scripts? So other maintainers keep the same pattern

@jefersondaniel yes! Sorry I didn't mean to force isort and black on this project. I forget that my IDE is running those checks.
