[issue12345] Add math.tau

[Lisa Roach]

Lisa Roach added the comment:

I have added some more detail to the Tau documentation, including that Tau is 2 * pi, as well as some links to Tau Day and Vi Hart's video. 

That should give Python users enough to get started forming their own opinions on tau vs pi :)
