Added project directory and gitignore.

Added project directory ShoppingList.  If we want we can change the name
of this, I'm just setting something up that we can work with and getting
comfortable with git.

Added gitignore and gitattributes file.  gitattributes was added by the
Github Windows client.  There's some settings in there that may be worth
looking at.

Removed program_docs\tmp.txt.
