Report the coordinates of the neighbors patches around the agents.

| torus | Logical to determine if the |
Matrix (ncol = 3) with the first column pxcor
and the second column pycor representing the coordinates of the neighbors
patches around the agents and the third column id representing
the id of the agents in the order provided.
The patch around which the neighbors are identified, or the patch where
the turtle is located on around which the neighbors are identified, is not
returned.
If torus = FALSE, agents located on the edges of the
world have less than nNeighbors patches around them.
If torus = TRUE, all agents located on the edges of the
world have nNeighbors patches around them,
which some may be on the other sides of the world.
