README.md shows wrong output

[MikeHopcroft]

Near the bottom of the readme, the output section actually shows the input files. This should show the chunk files instead.

Here's the output

$ ls -l sample-output/ total 8 -rw-r--r-- 1 Mike 197121 836 May 15 23:55 Frost.txt -rw-r--r-- 1 Mike 197121 1862 May 15 23:55 Whitman.txt
