  14: **  Paramize Quadrant Upon Entering
  15: **
  16: **	A quadrant is initialized from the information held in the
  17: **	Quad matrix.  Basically, everything is just initialized
  18: **	randomly, except for the starship, which goes into a fixed
  19: **	sector.
  20: **
  21: **	If there are Klingons in the quadrant, the captain is informed
  22: **	that the condition is RED, and he is given a chance to put
  23: **	his shields up if the computer is working.
  24: **
  25: **	The flag `f' is set to disable the check for condition red.
  26: **	This mode is used in situations where you know you are going
  27: **	to be docked, i.e., abandon() and help().
