Model-rocketry aerodynamics and trajectory simulation software

Role in this project:

Back-end Developer

Contributions:39 commits in 10 months

Contributions summary:Craig primarily contributed to the core data model and UI elements within the OpenRocket project. Their work included adding a `MassComponentType` enum for categorizing mass components, updating the `MassComponentConfig` dialog, and modifying the `MassObjectShapes` file to visualize the new mass component types in the rocket figure. Furthermore, the user implemented saving of the mass types to the configuration files, demonstrating focus on data persistence and integration. They also worked on adding helper functions to the component tree in the UI.
