Compute the area each triangle within the triangulation of points
        on the unit sphere.

        Returns
        -------
         area : array of floats, shape (nt,)
            area of each triangle in self.simplices where nt
            is the number of triangles.

        Notes
        -----
         This uses a Fortran 90 subroutine that wraps the AREA function
         to iterate over many points.
