+### Key features of UnityNodeEditorCore:
+* Lightweight in runtime
+* Very little boilerplate code
+* Strong separation of editor and runtime code
+* No runtime reflection (unless you need to edit/build node graphs at runtime. In this case, all reflection is cached.)
+* Does not rely on any 3rd party plugins
+* Custom node inspector code is very similar to regular custom inspector code
