Just trying to make it work...
Remove SCENE class. Adapt Figure.newWidget. some presentation change.
Change 'Qt.Vertical' to 'QtCore.Qt.Vertical'. Remove the createDialog function as it should be handle by the user class.
Remove tabs for space.
Merge branch 'SCENE-Correction' into TestGraphicsScene

Conflicts:
	LISA/Figure.py
	LISA/OGLWidget.py
	LISA/__main__.py
Remove conflicts for merging
