Pure Python implementation of the GR2M hydrologic rainfall-runoff model.
Requires Python 2.7 or 3.4 greater.
If Cython is available the Python code will be compiled by Cython during installation. Running the unit tests requires numpy and pandas. These dependencies are all optional as the base code is pure Python.
