Add an option to process nested functions

[dgutson]

Currently, radon only analyzes top-level functions or methods. Nested functions can be arbitrary complex but they are invisible to radon.
I propose a --nested flag.

it seems there is already a flag that shows nested methods...

  --show-closures       Add closures/inner classes to the output.
