New methods for Ints: .pick/1 and .choose/1 #127

The idea is that these implement the extremely useful (at least in combinatorics and statistics) operators of "pick" and "choose", usually rendered in textbooks as "nPr" and "nCr".

I'm open to better method names; "pick" clashes with .pick/2 on true and false.

Why not 'nPr' and 'nCr' as method names?
