Class description.
Hack hack hack.

I said two lines. At least.
I made some beautfication in the documentation.

Let's see if this changes in the documentation will
lead to some conficts. 

Yes it did. But I solved the conflict and kept the stuff
of Carlos anyway...

I did some weird stuff in the documentation. And then some more stuff.

    supported. Quantities is actively developed, and while the current features
    and API are stable, test coverage is incomplete so the package is not
