-# - For loop for the grid:

-#        - z is for creating cubes in the z axis. 
 # - I need to add the materials to the cubes and somehow save it in the Blender program. 
 # - I need to replace the nested for loop with a recursive function to spawn the ground. 
 # - I need to add a function to create a tree in a random position. This function will create cubes and put them in a way to look like a tree. It will also assign the correct materials to their proper cubes.
