Detailed Description

Calculate inverse of jacobian for face element.

It is assumed that face element is XY plane. Applied only for 2d problems.

Todo:
Generalize function for arbitrary face orientation in 3d space
Examples
cell_forces.cpp, hcurl_check_approx_in_2d.cpp, hcurl_divergence_operator_2d.cpp, minimal_surface_area.cpp, quad_polynomial_approximation.cpp, and reaction_diffusion_equation.cpp.
