refactor: Adding structure

Huge refactor to add better structure to the project.
Separating features with their associated view and model structure.
This should be better organization and will allow us to improve the
overall architecture in the future.

I forsee many more improvements that can follow this change. e.g. MVVM Arch
As well as cleaning up duplicate, unused, functionality.
Many files have global functions that can also be moved or be renamed.
