# Notes: 
# - For loop for the grid: 
#        - x is for creating cubes in the x axis. 
#        - y is for creating cubes in the y axis. 
#        - 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 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.
