So this is how I envision "installing a wheel to its own directory".

1. Unzip the wheel into its own directory.
2. If there are any nested *.data/purelib, platlib, make sure they are also
unzipped into the root of the unzipped wheel instead of their archive paths.
3. If there are scripts and you want them, install those too.

If 2 and 3 don't apply to you, you are done almost before you've started.
