Extend the output and partial derivatives of the output from the 2/3-D
...
table lookup models (XSPICE) continuously outside the defined
rectangle or cube, as it may help convergence and avoid ambiguity caused
by rounding at the boundaries. See bug #591 "Wrong 2D table model output".
The value is that of the nearest point in the region while the reported
derivative is ramped to zero outside the boundaries.
Also fixes incorrect output at the upper limit in each dimension.

Consecutive tran and ac simulation may lead to gross errors
...
when TC or scale is used on the instance line of C and L.
Reason is the missing reset when CKTtemp is called once during each
simulation command. TC or scale is then applied again and again,
a reset is missing.
This patch adds a reset, i.e. the capacitance or inductance is
reset to its instance value in a call to *temp. It fixes bug#594.
Command 'alter' has been tested.
Resistance has not been tackled by this bug, because the line
here->RESconduct = here->RESm / (here->RESresist * factor * here->RESscale);
differs from
here->CAPcapac = here->CAPcapac * factor * here->CAPscale;
in that there is no accumulation of correction factors with here->RESconduct

return 150
R2 n1 n2 r150
In case of r23mod return error = 1 and val = 0, so
r23mod may be read as a model, not an instance parameter

Update to plotting of event nodes:
...
Distance is now 1.5, scaling and cutouts are possible
(with some lack of precision).
Still missing: y axis labeling (no numbers, but node names).

Add a flag 'alle' (all event nodes) to the plot command (and maybe others).
...
All event nodes with length greater than 1 are translated to vectors
with a common scale (named step) and are assembled in a new plot
named 'digital'. They may be plotted or otherwise used in a
.control section.
