* G-API: Added G-API Overview slides & its source code - Sample code snippets are moved to separate files; - Introduced a separate benchmark to measure Fluid/OpenCV performance; - Added notes on API changes (it is still a 4.0, not a 4.2 talk!) - Added a "Metropolis" beamer download-n-build script. * G-API: Addressed review issues on G-API overview slides
