 +====== "freeze, unfreeze" commands ======
 +
 +===== Purpose =====
 +
 +"Freeze" to a point in time.  Remember circuit voltages and currents. 
 +
 +===== Syntax =====
 +
 +  freeze
 +  unfreeze
 +
 +===== Comments =====
 +
 +After the freeze command, the transient and fourier analysis will continue from the values that were kept by the freeze command, instead of progressing every time.
 + 
 +This allows reruns from the same starting point, which may be at any time, not necessarily 0. 
 +
 +===== Examples =====
 +
 +  transient 0 1 .01
 +A transient analysis starting at zero, running until 1 second, with step size .01 seconds. After this run, the clock is at 1 second.
 +  freeze
 +Remember the time, voltages, currents, etc.
 +  transient
 +Another transient analysis. It continues from 1 second, to 2 seconds. (It spans 1 second, as before.) This command was not affected by the freeze command.
 +  transient
 +This will do exactly the same as the last one. From 1 second to 2 seconds. If it were not for freeze, it would have started from 2 seconds.
 +  transient 1.5 .001
 +Try again with smaller steps. Again, it starts at 1 second.
 +  unfreeze
 +Release the effect of freeze.
 +  transient
 +Exactly the same as the last time, as if we didn't unfreeze. (1 to 1.5 seconds.)
 +  transient
 +This one continues from where the last one left off: at 1.5 seconds. From now on, time will move forward.
