If someone gives me this decorator, I will use it, but I don't know
how to write a decorator that works for all input and output cases,
and doesn't screw up our documentation system.
But I can change 2 lines per function, and I know I still have the
same signature and docstring. It looks like it will work for all
descriptive statistics and data transformation in scipy.stats. It
won't be relevant for most of the remainder.
