If a given dist
value is negative, then the turtle
would look backward.
If a given angle
value is negative, then the turtle
would look to the right.
If `torus = FALSE` and the `patch` at distance `dist` of a `turtle` and `angle` degrees to the left of its `heading` is outside the `world`'s extent, `NA` are returned for the `patch` coordinates. If `torus = TRUE`, the `patch` coordinates from a wrapped `world` are returned.
Matrix (ncol

column pycor
representing the coordinates of the patches
at dist
distances of the turtles

The order of the patches
follows the order of the turtles
