Hi,

I'm currently working with 3D DMPlex and performing crucial calculations 
involving face normals and edge tangents. I've noticed that face normals are 
directed from support[0] to support[1]. However, I'm uncertain about the 
conventions for edges and vertices in relation to faces. Specifically, I need 
to determine the order of vertices that create a surface and whether they are 
stored in a counter-clockwise (CCW) or clockwise (CW) manner. As DMPlex follows 
a hierarchy of cell-face-edge-vertex, my main question becomes about the 
orientation of edges. Any clarification on this aspect would be immensely 
helpful!

Additionally, I'm unfamiliar with most of the terms used in DMPlex. For example 
"orientation" in DMPlexGetConeOrientation. If you could suggest some readings 
or resources that explain these concepts, I would greatly appreciate it.

Thx,
Onur
