OO Symmetrys are now being drawn.
TODOs:
-Restore user interaction as it was before. (cycling through symmetry configurations)
-Faster symmetry drawing. (more inteligent ghosts object computation)
-Develop a way to load/save symmetry trees from files. (multiple trees if possible to have multiple trees)
-Develop a way to edit symmetrys in real time.
-Develop a way to add symmetrys in real time.
Fix: now no selectable object is selected when trying to select a non-selectable object.
