ENH: add utility method to display node in only 1 view

Since the view node id logic is set up to be backward compatible (no view node
id set means showing in all views), provide a convenience function,
SetDisplayableOnlyInView, that reduces this operation to one call.
It places the calls to remove all view node ids and add the new one inside of
a disable modified events block to avoid flicker.
Added testing.
