* Added guard for setting CUB_DIR to only when cuda variant is true * Added support for OpenMP on OSX platforms * Updated the way that LBANN, Hydrogen, and DiHydrogen handle apple-clang with OpenMP and Clang installed on OS X via brew. * Fixed bug in spec resolution * Fixed merge conflict * Fixed typo * Fixed flake8
