Strange failures because of package name collision

[hmijail]

There is a Pypi package named tdigest, which is linked to by the original author of the tdigest algorithm. That package gets installed with its name tdigest, as expected.

Tdigest-cffi also seems to get installed under the name tdigest by pip.

This will look OK if only one of the packages is installed. But if one tries to install both (as I did while trying to check their speed), it breaks: pipfiles and IDEs get confused.

In fact, there seems to be no way to cleanly uninstall tdigest-cffi from the pip CLI; I had to go into the package directory and delete manually both the tdigest and tdigest-cffi dirs.

It's a pity, because this package seems to be much faster than the other tdigest.

(I'm not experienced with pip/pypi, so there's the possibility that I'm missing some detail...)
