New issue 2517 by asmeurer: Decorator for requiring modules in tests
http://code.google.com/p/sympy/issues/detail?id=2517

From https://github.com/asmeurer/sympy/commit/b1e10b0e0b85a5a8d92441040819ad05eb20ed05#commitcomment-445587

It might be convenient to have a decorator like

@require(np, message="numpy not installed or Python too old.")
@require(scipy, message="scipy not installed.")
def test_scalar_scipy_sparse():
[…]

That handled the logic of skipping a test if the given libraries are not installed.

Also, should skip() be a decorator?
