Houville :: Get selections from Scene Views

This is one of those obvious needs that ends up being a frustrating "how do you even..?"

In Houdini 16.5 and up it's pretty simple:

import toolutils
sv = toolutils.sceneView()
str(hou.SceneViewer.currentGeometrySelection(sv))

However in 16.0 it's a bit more fiddly as currentGeometrySelection doesnt exist. hicon:/SVGIcons.index?book.svg

import toolutils
selection = toolutils.sceneViewer().selectGeometry() ## this annoyingly unselects your selection
print selection
## lets also get this in the clipboard so we can past it in a node.
