This module provides a function merge_sort, which is one of the simplest and the
most robust sorting algorithms, being relatively fast, having (n*log(n))
complexity. Also, this module counts the number of inversions in a given array.
Usage: import this module and use the function merge_sort. The first element in
a returned tuple shall be a sorted array, while the second one will be a number
of inversions in the array.
