optran is only selected when the 'optran' command has been processed.
...
If not, the call to the OPtran() function returns the previous
'converged' value.

Add command 'write_ic'
...
Write out the right hand side status of the matrix in format
.ic = V(node_xx)
This may be possible at the end of a simulation or after a 'stop'
of the simulation, which may be resumed again afterwars. This
status may be used to start another simulation with these
parameters by inluding into the netlist.

Transient op calculation added to the standard operating point code.
...
When standard iteration, gmin stepping and source stepping fail,
try a transient simulation (like tran with uic option) to
determine the op. Implemented for AC and Tran simulation.

Add new SOA parameters (safe operating area) for BJT.
...
We now scan for max of Ic, Ib, power, taking into
account the max allowed temperature, using the thermal
resistance rth0 model parameter between juntion and ambient.
Two user options are there: If rth0 is given, we calculate
a derating of the max power allowed.
Without a constant max power according to model param pow_max
is assumed.
The new model parameters for the bipolar model are:
pow_max, ic_max, ib_max, te_max, and rth0, in addition
to the already existing vbe_max, vbc_max, adn vce_max.

Add power and temperature limits.
Derating with self-heating, or with fixed temperature,
or no derating at all, selectable by setting model parameters.
