;; This is the missionaries & cannibals problem solved in Scheme.
;; The code is not as elegant as it could have been 
;; (lacking recursion, in the spirit of Scheme, in many places).
;; It is also not very generic. Also does no optimization and 
;; will apply search paths back and forth.

;; It works however, and should be relatively readable.
