distance_capsule_box_ccd - test_fcl_capsule_box_1 fails on mac.

[SeanCurtis-TRI]

PROPOSAL

Merge despite this CI failure until it is fixed. Please respond if you are uncomfortable with this proposal. Also looking for self-assignees to address it (most likely immediate candidates: @SeanCurtis-TRI or @amcastro-tri).

PROBLEM

Possibly related to #217

As of February 2018, PRs are running into CI failures on the indicated test. More particularly, PRs which apparently have nothing to do with the test.

Given that it is limited to the ccd version (the indep version passes across all of CI), the supposition is that there's a mac-dependent macro somewhere that is muddying the waters. It either lives at the interface between FCL and CCD for capsules/boxes or it's inside CCD proper.

The CI failure log is included below. Please note the deviation between expected answers and computed answers are wildly different; it does not seem to be a case of precision.
