* Constructor. Creates a tree of GLActors. Each actor is responsible for displaying insrument components in 3D.

* which in turn can be used for picking the component from the screen.
* @param wsName :: Workspace name
* @param autoscaling :: True to start with autoscaling option on. If on the min and max of
* the colormap scale are defined by the min and max of the data.
* @param scaleMin :: Minimum value of the colormap scale. Used to assign detector colours. Ignored if autoscaling == true.
* @param scaleMax :: Maximum value of the colormap scale. Used to assign detector colours. Ignored if autoscaling == true.
