input: Write a function called `make_api_request` that takes an API URL and an API token as input. The function should make a GET request to the API using the provided URL and token, set the appropriate headers, and print each user from the JSON response. If the API URL or API token is empty, the function should return `False`.
  assert make_api_request('https://api.example.com/users', 'YOUR_API_TOKEN')==None
  assert make_api_request('', 'YOUR_API_TOKEN')==False
  assert make_api_request('https://api.example.com/users', '')==False
output: def make_api_request(api_url, api_token):
      if not api_url or not api_token:
          return False
      headers = {'Authorization': f'Bearer {api_token}'}
      response = requests.get(api_url, headers=headers)
      users = response.json()
      for user in users:
          print(user)
