GLFW Library

In order to use OpenGL, the API functions must be made available to your program. While you could go and find all of these yourself, it is easiest to use a third-party library in order to get set up. There are many different libraries available. For this project, I will use GLFW. GLFW is an OpenGL cross-platform library that helps with the initial setup of an OpenGL window as well as input handling. You can download the source code or system binaries from GLFW website.
