Idiomatic Bubble Sort Performance

@Basarat: I created arrays of 10K and 50K random integers. I sorted the same array in nodejs using both bubble sort examples. The idiomatic example performs slower that the basic sort example. Is that expected?

```
##############################################
# #
***** bubble sort *****
# #
##############################################
bubbleSortProcessing-[10000]: 4758.006ms
earlyTerminationBubbleSortProcessing-[10000]: 4994.364ms

[nodemon] clean exit - waiting for changes before restart
[nodemon] restarting due to changes...
[nodemon] starting `node ./index.js`

##############################################
# #

bubbleSortProcessing-[50000]: 119734.447ms
earlyTerminationBubbleSortProcessing-[50000]: 125780.788ms

[nodemon] clean exit - waiting for changes before restart

```

I did notice a performance gain with Idiomatic sort using smaller data sets.
