Spice: taking a stab at working with equations

Two things need to be distinguished:
- Primitive equations that relate currents, voltages and time
- Spice's GV=I approach.

I'm currently more interested in building a good representation of the
equations, and then find mappings of that that will answer questions.
E.g. sensitivities: effect of circuit parameter on some computable

The full equation is a first order, non-linear differential equation.

The state variables can be currents and voltages.  However, they
generally are voltages, as inductors are rare and can be omitted on
the first try.  ( And could be replaced by gyrators? )

( Re-reading from october 2015.  Essentially going through the same
thing. )
