Detailed Description

The BoundaryFluxIntegral class calculates the line integral of the numerical flux along a boundary and saves it to a unique_distributed_variable.

Warning: Only works for 2D Cartesian and cylindrical coordinates.; Uses LGL nodes and weights. This will result in an error for nonlinear functions of the conserved variables, such as radial integral in cylindrical coordinates.

If _is_cylindrical = False: Calculates \( \int F \cdot \hat{n} dL \) along boundary line. Units for linear mass density flux are [mass * width^-1 * time^-1].

If _is_cylindrical = True: Calculates \( 2 \pi \int r F \cdot \hat{n} dr \) along boundary surface, assuming azimuthal symmetry. Units for mass flux are [mass * time^-1].

@TODO Generalize to 3D.
