Allow invoke to run from a custom script

[thedrow]

Invoke could also be usable for projects that are trying to write their own CLI interfaces. Therefor, it should be possible to call a method that parses the arguments and dispatches them to the right task.
More customization should be allowed in that script.

This is absolutely one of the design goals! :)

With the API as it stands, you can already do this. Check out how invoke/cli.py works. It leverages the (relatively well separated from each other) Parser, Loader and Collection classes. Any of those components can be used independently.

I'm closing this ticket itself as it has no real actionable todo items, but please feel free to open new ones after playing around with the existing class structure, if you have specific ideas for improvement. (These APIs are all rough drafts...)
