For monotonic plotting find out the majority of increasing or decreasing
x-axis values, add a warning to add 'retraceplot' to plot all if more than
10% of the values deviate from the majority.

The 8th parameter on a voltage or current source now is 'number of pulses'.
Previous usage had been PHASE, introduced by XSPICE, which has
been redundant to DELAY. PHASE is again available when compatibility flag
xs has been set.

Add behavioral (LOGICEXP, PINDLY) test for 283 circuit. There are glitches in the simulation for some of the s* outputs. Probably due to not having inertial delays. And why not set 'zero' delays as close to zero as permitted by XSPICE.
