Illumination info: For each integration point, ipt, we store all pairs identifying illuminating elements (via pointer to element and illumnating integration points):

Stefan_boltzmann_illumination_info[ipt].size() = number of illuminating elements Stefan_boltzmann_illumination_info[ipt][e].first = pointer to e-th illuminating element Stefan_boltzmann_illumination_info[ipt][e].second = vector containing index of integration points in e-th illuminating element that are visible from current element's ipt'th integration point.
