Rename internal classes to match documented terminology
We settled on the following names in the public API:
- geometry: points, curves, surfaces and volumes
- mesh: nodes and elements
We should refactor the internal classes to match those names:
-
GPoint
->GVertex
-
GVertex
->GPoint
-
GEdge
->GCurve
-
GFace
->GSurface
-
GRegion
->GVolume
-
MVertex
->MNode
