progressbar_demo.cir

Sweep progress-bar demo (Enhancement)
* -------------------------------------------------------------------------
* Run this interactively (or in batch) and watch the "Reference value"
* status line during the analysis:
*
*     ngspice progressbar_demo.cir
*
* Instead of just the current sweep value, ngspice now appends a live
* progress bar and percentage, redrawn in place every 0.25 s:
*
*     Reference value :  5.91926e-04  [==================      ]  74%
*
* The fraction is exact per analysis: transient uses elapsed time / TSTOP,
* AC / noise use the frequency's position in the (log) band, DC uses the
* swept-source position. This deck runs a long-ish nonlinear transient so the
* bar is visible; change the analysis line to .ac / .dc / .noise to see the
* same bar there.
