Added a test shader, updated main to use it
Shader loading can now take a shader of any size, vertex color depends on light position
Light calculation fixed
Added a fragment shader, renamed vertex shader file
Moved shader code to seperate files, cleaned up main slightly.
Added GLSL shader code.
The program now uses the glsl vertex shader.
