Iterative MNA Solver #324

Conversation

This branch implements a solver capable of solving nonlinear circuit equation systems. The implemented solver class "IterativeMNASolverDirect" inherits from "MNASolverDirect" and adds a solving method which uses the Newton-Raphson iteration algorithm. To be usable by this solver, for all nonlinear component models an interface class is provided which expects the nonlinear component models to implement a method returning the model's Jacobian of its system matrix equations for each time step to be used by the solver.

Since the Jacobian of a linear component's system matrix equation is the already implemented stamp, linear component models such as the Resistive Companion implementations of components are usable with the new solver, also in combination with new nonlinear component models using the new interface.

* change diode standard parameters (I_S, V_T)
* define mIntfVoltage as v1 - v0 so that connecting takes place from anode to cathode
- remove initialization related 'FIXME' comment
