doc additions
ENH: Add generic get_data_path function.

CPython docs warn that inspect.currentframe "relies on Python stack
frame support in the interpreter, which isn’t guaranteed to exist in all
implementations of Python." However, I tested this in PyPy too and it
works. Yeah!
STY: pep8
TST: Replace get_data_path
sphinx and doctest are insane.
