git-bats-demo solution, part 3 of 5 (creating a starter shell script)

This is the third of five videos that work through a solution to a simple shell scripting problem, using the bats testing tool to drive the solution.

In this part I create a simple starter script that gets us started. I show the use of `touch` to create an empty file, `chmod` to make that file executable, and add a "shebang" line that says that this should be interpreted as a sequence of `bash` command.

These videos assume that you know the basics of command line interaction (`ls`, `cd`, `rm`, etc.). if you're playing along at home you should definitely feel free to pause anytime I do something that appears mysterious and do a little searching for additional information.
