At the moment this code can calculate free electron gas and the SIAM (single-impurity-anderson-model)
In this version, the only thing computed by the code is the energy flow. There is no calculation for any thermodynamic quantaties.
The implementation is very slow and rather for educational purposes to get an idea of the NRG-method. For example: it is not considered, that only matrix elements between states, whos occupation number differs by one and S_z differs by 1/2.
There is only implicit parallelisation implemented by vectorizing the time consuming parts of the code.
