;ROOMMATES IN A HAT
;SPEC:  Every roommate gets a respective weight, based on which two are chosen (not the same two)
;       to clean the house.
;       Using a "pseudo-array" of strings bsaed on $ROOMMATE[1-6], we'll prompt the
;       caller for a weight [1-9], and make a corresponding array of integers (called $MATEWEIGT[1-6]).
;       Finally, bsaed on roommates weight, roommates are given a relative probability of drawing the
;       cleaning straw.  Two separate winners are put into $ClEANER[1] and $CLEANER[2]
