Because there are M wheels for any one sdist, we provide a directory
to cache them in, and then consult that directory when looking up
cache hits.
We only insert things into the cache if they have plausible version
numbers, so that we don't contaminate the cache with things that were
not unique. E.g. ./package might have dozens of installs done for it
and build a version of 0.0...and if we built and cached a wheel, we'd
end up using the same wheel even if the source has been edited.
:param link: The link of the sdist for which this will cache wheels.

WheelCachez�Wraps EphemWheelCache and SimpleWheelCache into a single Cache
This Cache allows for gracefully degradation, using the ephem wheel cache
when a certain link is not found in the simple wheel cache first.
