Vulkan initialization with GLFW and VK_CPP

Note to anyone who find this gist that I wrote it many years ago, at early days of vkcpp. Now vkcpp has been renamed to vkhpp, included in Vulkan SDK by default, and probably changed its internals quite a lot. So, you should consult examples and documentation from the SDK first... If you find those official documentation difficult to comprehend, curse the KH group.(The video programming community lacks a decent writer... almost all of them just know how to write man page)

I barely do any programming anymore, so I can't comment on the code
