/*
  This function iterates over a manifold, and interpolates the input function/field using the basis provided by the DS in our DM

  There are several different scenarios:

  1) Volumetric mesh with volumetric auxiliary data

     Here minHeight=0 since we loop over cells.

  2) Boundary mesh with boundary auxiliary data

     Here minHeight=1 since we loop over faces. This normally happens since we hang cells off of our boundary meshes to facilitate computation.

  3) Volumetric mesh with boundary auxiliary data

     Here minHeight=1 and auxbd=PETSC_TRUE since we loop over faces and use data only supported on those faces. This is common when imposing Dirichlet boundary conditions.

  The maxHeight is used to support enforcement of constraints in DMForest.

  If localU is given and not equal to localX, we call DMPlexInsertBoundaryValues() to complete it.

  If we are using an input field (DM_BC_ESSENTIAL_FIELD or DM_BC_NATURAL_FIELD), we need to evaluate it at all the quadrature points of the dual basis functionals.
    - We use effectiveHeight to mean the height above our incoming DS. For example, if the DS is for a submesh then the effective height is zero, whereas if the DS
      is for the volumetric mesh, but we are iterating over a surface, then the effective height is nonzero. When th effective height is nonzero, we need to extract
      dual spaces for the boundary from our input spaces.
    - After extracting all quadrature points, we tabulate the input fields and auxiliary fields on them.

  We check that the #dof(closure(p)) == #dual basis functionals(p) for a representative p in the iteration

  If we have a label, we iterate over those points. This will probably break the maxHeight functionality since we do not check the height of those points.
