* format and lint. changed "dir" argument to "mode"

* added pyspline solver test. this should fail until the pyspline pr #47 is merged. Updated the input file archive to include sabet's fuselage FFD

* flake fix

* minor tolerance adjustment on ffd generation test. this fails on my laptop with 1e-15 rel tolerance. the error is at 1.1e-15. Moved the tolerance to 1e-14, which should be plenty accurate

* addressing todos

* minor rewording

* addressing comments

Make ref axis optional when adding a child FFD (#150)

* added ref axis checks

* fixed refinalizing of child ref axis

* Update DVGeo.py

moved ref axis addition after the FFD coef are set to their original values to ensure ref axis is embedded in the undeformed volume.
