Description:
 def dimensionize(maybe_a_list, nd=2):
 """Convert integers to a list of integers to fit the number of dimensions if the argument is not already a list. For example: `dimensionize(3, nd=2)` will produce the following result: `(3, 3)`. `dimensionize([3, 1], nd=2)` will produce the following result: `[3, 1]`.
