SMARTcpp: a C++ extension of the rainfall-runoff SMART for Python

# SMARTcpp - a C++ extension of the rainfall-runoff SMART for Python

SMARTcpp is an open-source C++ extension for the hydrological catchment model SMART in Python. It is licensed under GNU GPL-3.0 (see [licence file](LICENCE.md) provided). SMART is a top-down rainfall-runoff model composed of a soil moisture accounting component and a routing component. It requires rainfall and potential evapotranspiration time series, it features a set of ten parameters, and it yields a discharge time series. This C++ extension is giving access to the calculation of the states, processes, and outputs of the model for one simulation time-step. It is intended to be used in combination with a wrapping script in Python, where the loop through the simulation time series is defined.
