Removed two unused functions (#4)

> Removed print statements to stop from polluting the Keypirinha console each time the main search box was opened and closed. As the functions are not used for anything else they could safely be removed.

Yes, this is what I added to distinguish the console output of this package from the clutter already present there. I literally forgot to remove these functions.

Thanks for doing this.
