This class generates the same type of immersed quadrature rules as those described in the FaceQuadratureGenerator class. The difference is that this class handles the case when the domain is a discrete level set function, i.e., when the level set function is described as a (DoFHandler, Vector) pair. The generate()-function of this class takes a cell in real space plus the respective face index and constructs the immersed quadrature rules in reference space over this face. These quadrature rules can then be obtained with one of the functions: get_inside_quadrature(), get_outside_quadrature(), and get_surface_quadrature().
Internally, the quadrature generation is done by transforming the discrete level set function from real space to reference space and using the same algorithm as in the FaceQuadratureGenerator class.

Constructor, the discrete level set function is described by the incoming DoFHandler and Vector. Pointers to these are stored internally, so they must have a longer lifetime than the created this class. The hp::QCollection<1> and AdditionalData is passed to the QuadratureGenerator class.

Construct immersed quadratures rules for the incoming level set function on a given face of the BoundingBox.
To get the constructed quadratures, use the functions get_inside_quadrature(), get_outside_quadrature(), get_surface_quadrature().
