* Update sorts/quick_sort_3partition.py
Another quick sort algorithm, returns a new sorted list
* Update sorts/quick_sort_3_partition.py
rename quick_sort_3partition to quick_sort_3part
* Update sorts/quick_sort_3_partition.py
rename quick_sort_3part to three_way_radix_quicksort
Three-way radix quicksort:
https://en.wikipedia.org/wiki/Quicksort#Three-way_radix_quicksort
First divide the list into three parts.
Then recursively sort the "less than" and "greater than" partitions.

* Delete sleep_sort.py
A silly algorithm designed to waste time. #2350 demonstrates that it is a 20+ second denial of service attack on every Travis CI run that we do.

* Update tim_sort.py
Update tim_sort.py
The previous algorithm was skipping numbers, according to issue #959, and my own tests.
The version I am applying uses a while loop, which works correctly and is easier to compute, as there is no break statement.
* Update tim_sort.py
* Added Whitespace and Docstring
I modified the file to make Pylint happier and make the code more readable.
* Beautified Code and Added Docstring
I modified the file to make Pylint happier and make the code more readable.

I added DOCSTRINGS and whitespace to make the code more readable and understandable.
* Improved Formatting
* Wrapped comments
* Fixed spelling error for `movement` variable
* Added DOCSTRINGs
* Improved Formatting
* Corrected whitespace to improve readability.
* Added docstrings.
* Made comments fit inside an 80 column layout.
Use the last element as the first pivot, for it's easy to pop, this saves one element space.
Iterating with the original list saves half the space, instead of generate a new shallow copy list by slice method.
* -Added a single-threaded implementation of odd-even transposition sort.
This is a modified bubble sort meant to work with multiple processors.
Since this is running on a single thread, it has the same running time
as bubble sort.
* -Added a parallel implementation of Odd-Even Transposition sort
This implementation uses multiprocessing to perform the swaps
at each step of the algorithm simultaneously.
* Adding variable to fade out ambiguity
* More readability on merge sorting algorithm
* Updating merge_sort_fastest description and explaining why
