CLI: should we autoinstall by default?

[josephjclark]

I want to say YES!

But the autoinstall process is actually quite slow (see #137 ).

I think that's because the CLI shells out to npm to tell if the adaptor has been installed. Maybe there's a quicker way we can do that to speed the CLI up.

The 1.0 release is a great time to make a change like this. Maybe it's better to automatically but slowly autoinstall and do a patch release later to speed it up

I think the answer is YES. I'll have a quick look at the performance but if it takes more than an hour I'll a patch a fix later
