SDE Parameterization

[markcampanelli]

Description

Consider using the inverse of shunt resistance, i.e., shunt conductance, to parameterize the SDE. The numerics generally work out a lot nicer, because, for example, the conductance parameter goes to zero (which is bounded!) as a PV device becomes ideal w.r.t. shunt resistance (which becomes infinite).
