Detailed Description

Ensures binding between opengl classes and the Qt interface. GLWidget inherits QGLWidget which inherits QWidget it gives to OpenGL the possiblity to integrate itself very nicely in most parts of the application. GLWidget contains an instance of the class Engine. There is also a slot supdate to force update and an "updated" signal is sent when it's done
