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).

new flag 'digitop' for the 'plot' command:
Plot digital (event nodes) vertically, separated by 0.1
The grid is adapted acordingly.
set xbrushwidth=3 will yield good results.

With the ngspice gnuplot command, enable x/y contour plots for 2d Cider save file data. Usage: gnuplot <file> xycontour <expr>. xycontour is a new flag which is ignored if the plot data is not from 2d Cider. For contours, only a single plotarg <expr> is allowed. With <expr1> vs <expr2>, only <expr1> is plotted and <expr2> is ignored.

Add variable 'plainplot' to allow plotting without
function support, but with node names incl chatacters like + - /.
Flag to command 'plot' is renamed to plainplot.
Error message added if vector not found.
Example file added.

If new parameter 'plain' is added to the 'plot' command,
all expression handling is skipped, vectors are plotting as is.
This allows nodes names with vectors like v(+vs) or /out
to be plotted without need resorting to double quotes.

When plotting arrays of curves, plot lines only in the direction
of (in absolute terms) growing x values.
Example: MOS output characteristics.
In the rare case of plotting versus varying x directions
(e.g. example memristor.sp), one has to add the flag
'retraceplot' to the plot command.

Set the color tables and linewidths personal for each graph,
added to strucht graph
Use only these data for plotting.
If zooming a plot windows, set as an extra parameter the graph id
of the 'mother graph'. Copy its color and line data to the new graph.
This is done by an extra parameter sgraphid to the internal plot
command that is issued in fcn PlotWindowProc().
Thus zooming will keep the background, text/line and graph colors.
Function setcolor() will always look into the colorarray of the
current graph.
