Clears runtime error that shows failure to create eigen vectors in problemState.
Small formatting changws.

1. Merge CollidingSceneObject into SceneObject. SceneObject is now optionally viewable
and collideable but not movable. SceneObject class has all the functionality of a static object.
2. Rename imstkLigUtility to imstkLogger
3. Rename virtualCouplingObject to virtualToolObject
4. Consistency with brackets for imstk namespace
5. Move enums that  into imstk scope unless if the enum has no meaning outside the class

To fix dependencies ambiguities with Collision

1) collidingobject needs to be virtual
2) trackingController was not passing scaling value

Used for camera controller, will be used for virtual tool
object. Useful to take care of world transformations (scaling,
offset, inverse translation, mirror rotations)

Adds memory.h for windows in cameraController to clear compiler errors

1) public constructor
2) add inversion flags
3) apply correct offsets and scales

still need to apply rotation offset based on
camera initial orientation

1) Camera does not hold a vtkCamera anymore (less tight integration).
It holds camera parameters.

2) Camera has a pointer to CameraController, that you can set up
based on a deviceclient. This camera controller has a reference
to the camera, and updates its parameters based on the deviceclient
retrieved information.

3) Scene runs the controller as an asynchronous module in its own
thread, it is therefore started in Scene::initModule and ended in
Scene::cleanUpModule.

4) In the timer loop of InteractorStyle, the vtk camera is updated
based on the scene camera.

5) In Renderer, a new vtk Camera needs to be created to match the
scene camera, since it is not created anymore in imstk::Camera.
