1.2.2.000:
- added Sort class
- added several array sorting functions to Sort class including:
- quick sort
- merge sort
- intro(spective) sort
- heap sort
- insertion sort
- tim sort
- selection sort
- bubble sort
- cycle sort
- cocktail sort
- tested all sorting algorithms with both lists and numpy arrays
- depreciated sort function from Array class
- added warnings as an import
