Compatibility: Linux, Mac, Windows
Putting 'dr_' (without quotes) in front of the node name makes it not renderable. On render time nuke disables them and enables them after the render.
The re module checks the front of the name, so it is not case-sensitive.
Put these lines into your menu.py
import im_dontRenderNodes
nuke.addBeforeRender(im_dontRenderNodes.dR_nodes)
nuke.addAfterRender(im_dontRenderNodes.r_nodes)
