The current commit removed Hoxu's gitstats and replaces it with gitstats.py.
This script has removed elements that create a .html and instead produces
a .txt output.
Removed gitstats, added gitstats.py

In the process of adding gitstats.py and cloning to a Mac, .DS_STORE
was added to the folder and this commit acknowledges that. Gitstats
deletion was necessary for replacement with gitstats.py
