Detailed Description

Builder for a molecular integration grid, using IntegratorXX

usage: GridBuilder builder; builder.set_nradial(nrad); builder.set_origin(gridcenter); builder.set_angular_order(order); builder.make_grid(); std::vector<Vector<double,3>> points=builder.get_points(); see test_IntegratorXX.cc for an example
