## Function to create an n-dimensional array

# Main function to call
# typeOfitem 
#     Should be a class which can generate objects
#     e.g. float, int, complex, or any other type, such as 
#     myCoolClass
#
# dimensions
#     value for a 1D array, or a list or tuple defining the
#     dimensions, for higher order arrays. e.g. a 3D array 
#     might be [2,3,4]
#
