Turtle and Observer Command
average-of-turtles-with `[1st list of commands] [2nd list of commands]` Returns the numerical average of the `[2nd list of commands]` when evaluated across all the turtles that satisfy the conditions (must return a boolean of true or false) specified by the `[1st list of commands]`. Note: If `[2nd list of commands]` contains no numbers, an error occurs. If some of the `[2nd list of commands]`, when evaluated, are not numbers, those values are ignored. Note: When a turtle calls the command, it is not included as part of the calculation. Examples: `average-of-turtles-with [color = red] [energy]` returns the average energy of all the red turtles.
