object.group_users, object.scene_users
utility functions to find the groups and scenes this object is used in.

button to set the group location from the cursor (UI is horrible but not any nice place to add?)

smarp project would fail if there were linked meshes in the scene, made ID.tag ignore the library, so you can tag linked data since its only for tools to use.

normalize the vertex normal before setting and use inline vector functions.
