c   mfood = total initial number of food particles
c   msteps = max number of simulation steps
c   wint = ant-pheromone interaction strength (attractive if positive)
c   wint2 = ant-pheromone interaction strength for pheromone 2
c   tau = pheromone lifetime (number of steps to reduce pheromone 
c         level to about 30% of its original value)
c   foodpersite = number of food particles/lattice site
c   wdelay = walker release period (in steps)
c   lattype = 1 if square, 2 if triangular
c   baserunid = base filename for output files (e.g. runid.ps)
c   outres = output resolution (max number of pixels in each direction)
c   dwrite = period (in steps) of diffusion constant and food 
c     efficiency output to file
c   initseed = initial seed value
c   write_ps = 1 if you want .ps files to be created, 0 if not
c   showwalkers = 1 if you want walkers shown as red dots in .ps file
c   foodrate = number of food/step added to the system (food is added
c     in chunks of foodpersite)
c   fooddecay = food lifetime -- every x steps, the food on a site is
c     reduced by a factor of  1 - (1/fooddecay)
c   decaydelay = x (the number of steps between food decays)
c   writefreq = how often (in steps) the nfood value is written out
c   showfood = 1, if you want the initial food distribution to be 
c     shown in the Postscript picture as green outlines
c   viewerout = 1, if you want the program to output system information
c     every z steps (for AtomViewer-like displaying)
c   viewfreq = z (the number of steps between file outputs)
c   npher = number of different types of pheromone
c   nscouts = how many of the total mwalkers are scouts (the rest are
c     workers) -- this parameter is ignored if npher = 1
c   binwidth = the width (in units of lattice sites) of the bins for the
c     calculation of g(r).  Must be greater than or equal to 1.0.
c   viewdelay = the number of steps to wait before recording to .v file
c   greynorm = greyscale normalization for the Postscript output -- if
c     the keyword is omitted, it automatically normalizes
c   inertia = the probability of a walker going forward rather than
c     sideways, when it is not next to any pheromone, food, the nest,
c     or other walkers.
