Custom Point Annotations

[BryonLewis]

Adds optional point annotations to each detection in DIVE.

User Perspective:

• Add capability to create points of interest for detections in a track

• These points should be able to be labeled and have a custom color

• Points can only be added after creating a boundingbox

• Points can be grouped together in a hierarchy

• Points can be selected, modified and edited

• Would be nice to have a way to bind custom keyboard shortcuts to the creation of specific point types

• Adds additionalPoints to the track structure and options on how to update the fields

• additionalPoints can be a set of points where each point has it's own label.

TODO:

• Add base editing system for points
  • Points should only be available once a bounding box is created for a detection
  • Points can be selected after selecting the track for editing by clicking on them
  • Existing points can be modified by dragging or deleted by selecting and clicking 'delete point
• Within the configuration file there can be specific colors tied to specific labels.
• Add ability to color points by labels
• Add sizing and adjustment to point size and point label text size
