How to get individual RGB channels from node with API?

[AaronWPowell]

For example, if I have a curvature node, from what I can tell it only exports the RGB output when you link it to another node. But what if I want JUST the R channel (for convex data), or the G channel (for concave)? Do I need an `rgb_to_float` node, or is there another way to link the curvature node to the graph so I get the channel I want?

Of course, I figured it out after I posted. I didn't realize this before, but I should use the `AiNodeLinkOutput()` command to specificy the channel I want. Will test to confirm later.
