Gets the area of the cell.
An application does not need to override this method.
| [in] | meshGeometry | The geometry of the mesh. Used to retrieve the node coordinates of this cell. |

Gets the number of edges.
For non linear cell, the number of edges is independent of the order of the cell. For instance, getNumEdges will always return 3 for a linear triangle cell, a quadratic triangle cell, a cubic triangle cell etc...
