Upgrading and multi-components

[davatron5000]

Howdy! I really like this project. @thepassle told me to file feedback here.

I was playing around with npm init @open-wc this month and I had two questions/ideas...

1. It's not clear what Upgrade Existing Project is supposed to do or where I'm supposed to run it. Does that only work for any app? Only project made with open-wc? Do I do run the command outside of the project scope like the Scaffold a new project? Maybe it's related to #58 and it actually does nothing right now, which is why I was confused?
2. You get the choice to scaffold a component, but if you want to add another component you have to create a whole new folder. Is this for monorepos? Maybe an Add another component option would be nice for building out components in a design system or an application. Then I could get a component file, test file, and a stories file?

Let me know if I'm not making sense.
