How do we fix the model in VR space without moving anywhere? IUsusally when we move the model using controllers we can move it. But I want to fix the model in the surface.

@cpinter could you add the node attribute name that controls movability to the [developer guide](https://github.com/KitwareMedical/SlicerVirtualReality/blob/master/DeveloperGuide.md)?

I updated the guide, see the bottom of the page.

Also I added a feature in the Data module where you can set this flag in the context menu of nodes and folders, but I think it’s not updated in the downloadable extension yet. I’ll do that very soon.

I tried but there is an error by saying " NameError: name ‘nodeLocked’ is not defined"

`nodeLocked` refers to a MRML node object. You can use `nodeLocked=getNode("My node")` to get a node object from node name.
