NXLauetof (NMX specific) loader

[YooSunYoung]

We can now save NXLauetof file but we don't have a loader.
The loader or the loaded object should be able to resolve the geometrical information (i.e. position vectors)
so that we can easily see the 3D instrument view from it.

Oh top of this, we want a viewer that shows 3d instrument view from the NXLauetof file

And save the probability (floating numbers) together...! (Or just be able to plot it ... I don't know... )
