Using example program for framework test
Added framework to cmake
Commiting Lesson 13 Visual Studio project

Could not compile the rendering framework using cmake or to render with
clang.  Possible can fix by writing a manual make file but until I try
that I will use windows.  Falling behind with work and can't have that!
Updated .gitignore

Removed project .sdf file

This is just a database of things for intellisense in visual studio, it is also
