atl_covolume_to_primal_projection

public function atl_covolume_to_primal_projection(left, right, dir, filter, scheme, maxPolyDeg, nScalars, state) result(primal)

This routine projects two co-volume elements (left and right) onto its primal element. The geometrical setup is as follows:

     left (co-vol.)       right (co-vol.)

|---------------------||---------------------| \ / \ / | |/ |---------------------| primal element

The transformation to the primal element is carried out by a simple (but efficient) L2-projection.
