Make Info and Verbose argument flags mutually exclusive

[Vadoola]

Part of how I resolves issue #11 was to turn off info printing by default. As the main use for a lot of people is probably through QElectrotech this probably makes sense. However if you are running it from the CLI, it probably makes sense to default to printing the info.

It's a low priority but I should be able to make the info and the verbose options as mutually exclusive by using an enum with clap. I've never tried this but I'm pretty sure this is possible. That way it defaults to printing the info, but when the -v flag is used it disables the info as well.
