Dense matrices and low rank approximation

Several examples show how to combine low rank approximation techniques with the provided integral methods:

1. HSS/HODLR applied to PEEC with 1D elements
2. HSS/HODLR applied to PEEC with 2D quadrilateral elements (Axisymmetric - Coulombian formulation)
3. HSS/HODLR applied to Volume Integral with tetrahedral elements
