# This file defines a function random_array(id, size, max) that
# returns a random array with the given size.  Each element in the
# returned array is an integer between 0 (inclusive) to max
# (exclusive), or a real number between 0 and 1 when max==1.  It
# returns the same array when it provided the same set of parameters.
