/**
* A #ViewerPath is a path to data that is viewed/debugged by the user. It is a list of
* #ViewerPathElem.
*
* This is only used for geometry nodes currently. When the user activates a viewer node the
* corresponding path contains the following elements:
* - Object the viewer is activated on.
* - Modifier that contains the corresponding geometry node group.
* - Node tree path in case the viewer node is in a nested node group.
* - Viewer node name.
*
* The entire path is necessary (instead of just the combination of node group and viewer name),
* because the same node group may be used in many different places.
*
* This file contains basic functions for creating/deleting a #ViewerPath. For more use-case
* specific functions look in `ED_viewer_path.hh`.
