# Creates a matrix given an object or set of objects around a point, which serves as the lower corner
# Inputs:
#          1) Number of duplications in X direction
#          2) Random number modifying arg 1.
#               E.g. if Arg 1 is 5 and Arg 2 is 3, then possible number of objs in X ranges from 2-8,
#                    varying based on a random number draw
#          3) Same as 1) but for Y
#          4) Same as 2) but for Y
#          5) Same as 1) but for Z
#          6) Same as 2) but for Z
