* Add benchmark using timeit
https://docs.python.org/3/library/timeit.html
The performance delta between these two implementation is quite small...
```
next_greatest_element_slow(): 1.843442126
next_greatest_element(): 1.828941414
```
* Optimize slow() to create fast() - Three algorithms in the race
Three algorithms in the race
* Use a bigger test array with floats, negatives, zero
* Setup import next_greatest_element_fast
