The document contains code for several classes related to building a Unity game hierarchy and importing assets. Key points: - The Hierarchy class contains code for displaying foldout headers to organize game objects in a hierarchy. - The BuildRoot method builds a tree structure containing animal category names and species for display in a hierarchy. - The CubeImporter script imports cube assets from JSON files, setting the cube position from the file data. - Editors are created for the CubeImporter and Object classes to customize their properties in the inspector. - The E03_StyleSheet class applies a style sheet to container elements for visual formatting.
