atl_primal_to_covolume_projection_2d Subroutine

public subroutine atl_primal_to_covolume_projection_2d(left, right, dir, filter, scheme, maxPolyDeg, covolume, order)

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

     left                 right

|---------------------||---------------------| \ / \ / | |/ |---------------------| co-volume

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