Contributions summary:Dylan primarily contributed to refactoring and restructuring the JanusGraph codebase. They removed unused imports, renamed classes and interfaces (e.g., TitanGraphTransaction to Transaction, TitanIndex to Index), and moved functionality to different classes. A significant portion of their work involved adapting the code to the TinkerPop 3.2.x API, focusing on the FulgoraGraphComputer. These changes likely improved code maintainability and compatibility with external libraries.
