input: Write a function that takes two numbers as input and generates a random number between them, inclusive.
  
  def random_number_generator(min, max):
      return random.randint(min, max)
  
  assert random_number_generator(2, 5) in [2, 3, 4, 5]
  assert random_number_generator(0, 1) in [0, 1]
  assert isinstance(random_number_generator(-10, 10), int)
  
  ### Explanation:
  - The function `random_number_generator` takes two arguments, `min` and `max`.
  - It returns a random integer between `min` and `max`, inclusive.
  - The random module is assumed to be imported.
  
  Thus, the function can be used to generate a random number between any two given numbers.
output: def random_number_generator(min, max):
      return random.randint(min, max)
