/*
**  BOARD A KLINGON
**
**	A Klingon battle cruiser is boarded.  If the boarding party
**	is successful, they take over the vessel, otherwise, you
**	have wasted a move.  Needless to say, this move is not free.
**
**	User parameters are the Klingon to be boarded and the size of
**	the boarding party.
**
**	Three things are computed.  The first is the probability that
**	the party takes over the Klingon.  This is dependent on the
**	size of the party, the condition of the Klingon (for which
**	the energy left is used, which is definately incorrect), and
**	the number of losses that the boarding party sustains.  If too
**	many of the boarding party are killed, the probability drops
**	to zero.  The second quantity computed is the losses that the
**	boarding party sustains.  This counts in your score.  It
**	depends on the absolute and relative size of the boarding
**	party and the strength of the Klingon.  The third quantity
**	computed is the number of Klingon captives you get to take.
**	It is actually computed as the number of losses they sustain
**	subtracted from the size of their crew.  It depends on the
**	relative size of the party.  All of these quantities are
**	randomized in some fashion.
