Detailed Description

Class representing projection operator between a high-order L2 finite element space on a coarse mesh, and a low-order L2 finite element space on a refined mesh (LOR). We assume that the low-order space, fes_lor, lives on a mesh obtained by refining the mesh of the high-order space, fes_ho.
