We need access to the area of a grid cell for

  • BBM's scaling of cohesion
  • Coupling within the NorESM framework (and probably others as well)

The current smesh.area() function does not report the correct area for meshes with a lat/lon coordinate system.

@winzerle will use the mapings determinant J in ParametricTools, with a cosinus of latitude included.

The units returned by smesh.area() should be metres (m).
