> The sorter should work for any type of vectors, with a time complexity of O(n*log( n )). 
> Since it does not make any assumptions about the memory layout of the vector, its performance can be sub-optimal. So if another sorter is applicable (e.g.{{FixedWidthInPlaceVectorSorter}}), it should be used in preference.
