Use the current point number as the single digit index for Cider 2D ascii save files. This conforms to the normal usage with other types of ascii rawfile. The numd parser table entry for ic.file now has the correct IF_STRING type.

Retaining the mixed case of Cider quoted string valued parameters. Limit searches for ic.file to D*, M*, and Q* device instantiation lines. Cider model (numos, numd, nbjt) detection is limited to .model lines. Continuation lines which do contain these tokens are not checked, but this should rarely happen. All of the examples/cider circuits meet these assumptions. Memory errors have been removed.

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.

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.
