Make a release

[aborrero]

Hi there!

I'm planning to package NeoPI for Debian.

For this to happen, it would be nice to make an official release of NeoPI. By an official release I mean: hardcode the version in the script (maybe show it with -h), tag the commit that contains the versioning stuff as the release and push the tag to github.

For the versioning scheme, I would suggest something like '0.1', given this is the very first release.

Also, It would be recommendable to add copyright headers to all files.

Please, let me know your thoughts.

regards.
