Displayable manager: Specialized logic handling both RenderWindow <-> MRML and RenderWindow <-> Logic interactions.

Motivation: Have a well-designed mechanism to ...
- ...represent MRML node within a Renderer/RenderWindow.
- ... handle mouse/keyboard interaction.
- ... synchronize widget across different views.

Overview:
- Each time a viewer is instantiated, it asks a factory to provide him with a DisplayableManagerGroup.
- DisplayableManagerGroup contain a list of DisplayableManager
- Each DisplayableManager is associated with Renderer + InteractorStyle

DisplayableManager
- Currently, there are two type of DisplayableManager: ThreeD and Slice DisplayableManager - Similar API.
- Both derive from vtkMRMLAbstractDisplayableManager.
- ThreeDDisplayableManager [1]: deals with MRMLViewNode / ThreeDInteractorStyle
- SliceDisplayableManager [2]: deals with MRMLSliceNode / SliceInteractorStyle

Factories:
- vtkMRMLThreeDViewDisplayableManagerFactory
- vtkMRMLSliceViewDisplayableManagerFactory

DisplayableManager within Module
- Module can also register DisplayableManager. See qSlicerAnnotationsModule.cxx#L65

DisplayableManager and Python
- Mechanism to load python based DisplayableManager
- Achieved using vtkMRMLScriptedDisplayableManager

List of DisplayableManager (available in Libs/MRML/DisplayableManager directory)
