function antpath(ntime,x,y,direction,npellets,looked)
%ANTPATH    Stores the path taken by the GPLAB artificial ant.
%   ANTPATH(NTIME,X,Y,DIRECTION,NPELLETS,LOOKED) stores the path
%   taken by the ant, step by step.
%
%   Input arguments:
%      NTIME - the current time step on the ant evaluation (double)
%      X - the current X position of the ant on the trail (double)
%      Y - the current Y position of the ant on the trail (double)
%      DIRECTION - the current direction the ant is facing (char)
%      NPELLETS - the current number of pellets eaten (double)
%      LOOKED - whether the ant just looked ahead (boolean)
