-The cross platform calculator illustrates how to use Nim to create a backend
-called by different native user interfaces.

-Since the purpose of the example is to show how the cross platform code
-interacts with Nimrod the actual backend code is just a simple addition proc.
-By keeping your program logic in Nim you can easily reuse it in different
-platforms.
-
-To avoid duplication of code, the backend code lies in a separate directory and
-each platform compiles it with a different custom build process, usually
-generating C code in a temporary build directory.
