input: Write a python function to calculate the mean, median, and mode of a list of numbers.
  assert MeanMedianModeCalculator().calculate_mean([1, 2, 3, 4, 5]) == 3
  assert MeanMedianModeCalculator().calculate_mean([5, 10, 15]) == 10
  assert MeanMedianModeCalculator().calculate_median([1, 2, 3, 4, 5]) == 3
  assert MeanMedianModeCalculator().calculate_median([5, 3, 1, 4, 2]) == 3
  assert MeanMedianModeCalculator().calculate_mode([1, 2, 2, 3, 4]) == 2
  assert MeanMedianModeCalculator().calculate_mode([4, 4, 4, 4, 4]) == 4
output: from statistics import mean, median, mode
