    Add lines, loads, generation and storage for electrical neighbours

    This dataset creates data for modelling the considered foreign countries and writes
    that data into the database tables that can be read by the eTraGo tool.
    Neighbouring countries are modelled in a lower spatial resolution, in general one node per
    country is considered.
    Defined load timeseries as well as generatrion and storage capacities are connected to these nodes.
    The nodes are connected by AC and DC transmission lines with the German grid and other neighbouring countries
    considering the grid topology from ENTSO-E.
