Soon, import functorch will work after one installs PyTorch. However,
we want to maintain backwards compatibility for installing functorch
from source (because many folks do that).
This PR:
deletes most of the code in functorch (which has already been
moved to the pytorch/pytorch repo)
sets up a "dummy package" -- installing functorch from source will
install something that has no imports. import functorch will work by
virtue of the functorch dummy package requiring torch as a requirement,
and the torch binary will enable import functorch.
leaves the README.md and some other necessary metadata (license,
CONTRIBUTING.md, etc) intact.
Test Plan:
I tested that one is able to build a dummy package and upload to
testpypi
