[KLMB/OBJECT/TRANSFORMATION TREE]: created a 'transformation tree' (this is not a scene graph).
[KLMB/OBJECT|CAMERA]: updated to follow changes in yaggler::geometry / bugfixes to allow camera switch.
[YAGGLER/GEOMETRY]: yaggler::geometry is now compatible with glm primitives, and could be used to load/render objects from a dynamic source of content. (a file, procedural, ...)
[KLMB/SAMPLE/DRAGON]: added a nice stanford dragon and a lovely shader :)
