GSoC 2021 - Week 1 - Generalized Popups for Notation Elements

A major part of the functionality of my project is contained within a popup under the tempo element which appears when the tempo element is being edited. I spent my first week coming up with a system that allows customizable popups to be positioned under any editable notation element. This popup will tie in with the existing Inspector Settings Models and work in tandem with the inspector popups.

This is how the popup looks in action.

Over the course of the next week, I plan to add in the UI needed for the Tempo Popup, and possibly add in the functionality to get some of it working.
