function guess(a,b)

% GUESS ....... guessing game.
%
%     GUESS(A,B) given certain information of a person (age, height or
%		weight as specified by the input argument A),  you are asked
%		to guess the other piece of information as specified by the
%		input argument B for the same person.  Valid options for the
%		input arguments A and B are:
%
%			'age'           'height'        'weight'
%
%		You score a correct guess if:
%		    1) true weight and your guess is within +/- 5 kg.
%		    2) true height and your guess is within +/- 5 cm.
%		    3) true age and your guess is within +/- 2 year.
