/*
**  Ask a Klingon To Surrender
**
**      (Fat chance)
**
**      The Subspace Radio is needed to ask a Klingon if he will kindly
**      surrender.  A random Klingon from the ones in the quadrant is
**      chosen.
**
**      The Klingon is requested to surrender.  The probability of this
**      is a function of that Klingon's remaining power, our power,
**      etc.
