/**********************************************
*  getwired - do the wire routing.            *
*					      *
*    When getwired is called, the signal list *
*  is sorted in order by signalname.  This    *
*  routine connects adjacent pins with the    *
*  same signal name together.  Pins are conn- *
*  nected together with either top to top     *
*  wraps or bottom to bottom wraps everywhere.*
*  The last wrap may really be wrapped as a   *
*  top to bottom wrap if there is an odd num- *
*  ber of pins in the string.  But it is still*
*  represented as a top to top wrap.	      *
