MVC Architecture

[mictab]

Description

• Refactoring main.py a bit
• Extracted some things to StreamModel
• Helper method in main for binding UI to actions

A lot of necessary logic was already moved to VideoFrameGrid and thus the StreamModel does not contain as much as before. We can further refactor later.

Important files to review

main.py models/model.py
