 ## Termbox
 Termbox is a library that provides a minimalistic API which allows the programmer to write text-based user interfaces. The library is crossplatform and has both terminal-based implementations on *nix operating systems and a winapi console based implementation for windows operating systems. The basic idea is an abstraction of the greatest common subset of features available on all major terminals and other terminal-like APIs in a minimalistic fashion. Small API means it is easy to implement, test, maintain and learn it, that's what makes the termbox a distinct library in its area.
