Vcpkg (and cmake) support.

Hello,

I have recently written an overlay port for this library, along with a basic cmake file, and wanted to share it with you.
dsharlet-array.zip

I did not want to merge it directly into https://github.com/microsoft/vcpkg since it is your library.

Hi, thank you for this!

I'd be happy to add the CMakeLists.txt to the project, I'd be happy to either accept a PR or add it myself, either way. If we do add it, I'd like to also get it hooked up to travis at least as a build test to make sure it stays healthy.

As for the vcpkg, I'm certainly not opposed if you want to add it to microsoft/vcpkg. I don't see any notion of ownership there. I don't have a VC++ installation currently to try it out, I can try to get one soon. This also motivates coming up with a better (more distinctive) name than 'array'. Naming is hard...
