 TODO
 ==========
--Change the logger class to use cout instead of printf. Consider how easy variable argument support would be.
- - What I really need to do is completely refactor the logger class to return an ofstream to the logger file
-   and use streaming to send output to it. The log file can be closed in the destructor.
 -Add code to allow for resizing/maximizing the window
  - Doesn't seem to be necessary on OSX anymore, check that in works on Window and Linux, including removing
    the window title bar in fullscreen mode and bringing it back in windowed mode
+ -Update the IMGUI code in a generic way to support this as well
 -Check the book's "Printing Parameters from the GL Context" to output a bunch of OpenGL context params
 -Move some common functions into a Utils class

 -Make sure fullscreen works correctly on OSX. Check the book to see how to handle Retina Display.
 -Change all error messages to use the logger class so they get printed to the log file as well.
