description         Usadel equation solver

long_description    This code solves Usadel equations in a circuit consisting of quasi-1D \
                    metallic wires. This is an efficient approach for modelling charge and heat \
                    transport in mesoscopic electronic circuits made of superconducting and normal-state \
                    metals, in the presence of a sufficient amount of impurities (dirty limit).
