  turtle-count       ; The total number of turtles
  ticks              ; The number of times through
  energy-from-berries; How much energy lost from eating poison berries
  berries-grow-rate  ; How fast the berries grow
  ave-intelligence   ; The average intelligence of all turtles
  ave-energy         ; The average energy of all turtles
  ave-carnivorous    ; The average 'carnivorous' of all turtles. Higher 'carnivorous' means more preference to meat

turtles-own[
  actions         ; number of actions the turtle can do per turn
  age             ; number of ticks the turtle has been around (range: >= 0)
  aggresive       ; high aggresive means turtle is more likely to attack other turtles (usual range: 0-1)
  berries-eaten   ; the number of times the turtle has eaten berries (range: >= 0)
  carnivorous     ; the degree to which the turtle prefers meat. 0 means only likes grass.  1 means only likes (to eat) other turtles (usual range: 0-1)
  chasing?        ; is this turtle after another? (range: true or false)
  color-digit     ; The represents the base color of the turtle (range: 1, 2, or 4).  It is an indication of aggresiveness
  energy          ; The total amount of energy the turtle has. < 0 and turtle dies (range: > 0)
  fighting?       ; Is the turtle fighting? (range: true or false)
  fight-partner   ; Who is the turtle going to fight? 
  fight-tools     ; things such as teeth, claws, and power (usual range: 0-1)
  food-storage    ; the amount of food (energy) can a turtle hold (range: > 0)
  intelligence    ; how smart is the turtle (how logical its decisions are) (usual range: 0-1)
  likeness        ; how similar a turtle is to a potential fight partner.  This only has relevance in attacking situations
  move            ; how far the turtle has moved this turn
  reproduction-threshold ; at what energy level will the turtle reproduce (range: > 0)
  sight           ; the number of patches the turtle can see (range >= 0)
  speed           ; number of patches a turtle can move each turn (usual range: 0-1)
  wander-strength ; how much influence does 憌ander direction
