Specify ascending/descending property for comparison based sorts

Details:

Comparison based sorting algorithms can have two results: the object is either sorted in ascending or descending order. From what I see, most of the algorithms submitted here assume ascending order, but this can be easily resolved if an additional boolean parameter is passed to the sort function to specify the ascending/descending property. This would also entail changing the test files which depend upon the sort function accepting only the object as a parameter.
