- Can be translated locally or moved to a point in the world
- Rotates locally around local x- and z-axis and around global y-axis.
Added key checks to test camera movement.
Added Quaternions (Inherits from CoordinatesVector<double,4>) with a view to handling the camera orientation.
Added equality operators for CoordinatesVectors.
Removed slow `glutGet()` calls.
Added custom reshape callback as we now store the window parameters to avoid some `glutGet()` calls.
Renamed `KeyStateManager` to `InputStatus` as it handles more than key states now.
Mouse movement callback now captures the cursor, handles its re-centering and when the cursor enters the window far away from its last position.
TODO : Consider limiting rotations for the camera (Prevents flipping the head around)
