Detailed Description

Connects continuous to discrete.

The GeometricEntity object encodes a physical geometry by dimension and can maintain a list of all discrete mesh entities that are associated with the given geometrical object.
Here is a brief description of the types of objects we can represent with a GeometricEntity and their interconnections:

dim  discrete   physical
---  --------   --------
0     Node       Point
1     Edge       Curve
2     Face      Surface
3    Region      Volume
