* update directories for caching homebrew packages
* add include path for mac os high sierra and opencv3
* refactor OpenCV wrapper to use static C functions
* circleci: (23 commits)
update cache number
explicit path list, as circleci does not support variables
use environment for cache paths
add script to install opencv
install OpenCV with one level dependencies
add deep brew dependencies link opt
update pods
update bundle
optimize brew cache for opencv
optimize pod update

move test stage before deploy
skip cache on deploy
add name to deploy, remove env
fix stages
move Deploy to a stage
add names to job in matrix, extract maintenance
