> TestUtils.assertRelativelyEquals() generates misleading error on failure.
> For example:
> TestUtils.assertRelativelyEquals(1.0, 0.10427661385154971, 1.0e-9)
> generates the error message:
> junit.framework.AssertionFailedError: expected:<0.0> but was:<0.8957233861484503>
> which is not very helpful.
