"...resnet50_tensorflow.git" did not exist on "a6c6089b593eff03c68e174c30b8b947a1c20f93"
Moved all the includes to a subfolder yaml-cpp so they don't interfere with other libraries' includes
Added emitting for a YAML::Node (instead of the ad-hoc std::ostream overload) so it'll actually emit valid YAML always
