Inspiration

Inspiration for this is taken from jakeheis/SwiftCLI. SwiftCLI does more than just run a system process. It also makes Commands, a structured way to add arguments and options to a process you run on the commandline. As for commands we use Apple's swift-argument-parser SwiftCLI was too big to use. But the way to run a task is taken from that project and used here.
