"git clone" part's format is changed to source code.
src Folder, Automatically Add New Files
* src file is created. You can work on there.
* .h and .cpp files under "src" folder will be added to project after
re-run the CMake.
* Glew support is added. Just #include <GL/glew.h> to use it.
Some small edits for README.md.
