Minor changes to get cpal to import

I was getting an error when I tried to 'import cpal' due to the indentation on the multiline comments at the beginning of cpal.py and cisco.py.  Consequently, I just removed this indentation.

I also added a .gitignore file to ignore .pyc and .swp files.  I removed the README.md~ file (which github misinterpreted as a rename below).

I then added a blank __init__.py to make the cpal directory a package.  So I can import it from outside of this directory as 'import cpal.cpal'
