''' Define test function for scipy package
Module tests for presence of useful version of nose. If present
returns NoseTester, otherwise returns a placeholder test routine
reporting lack of nose and inability to run tests. Typical use is in
module __init__:
from scipy.testing.pkgtester import Tester
test = Tester().test
See nosetester module for test implementation
