FULLY ANIMATED LOOKUP CURVES
aniLookup is a fully animatable Lookup node, that also doubles as a ColourMatch.
It's a macro based on one Lookup node, so it's fast. To keep it fast, the overlays are only constructed when you turn on OverlayCurves. It's built with a small Ramp, a Lookup, a PlotScanline, an OpenGL generated image & 2 Overs. I added this so that you could see what the curves are doing. The JSplines can have 3, 5 or 7 control vertices. The control vertices are controled with the Source & Destination rgb pallettes/curves. Source controls the time or X position of the vertice, Destination controls the value or Y position. The Source & Destination pallettes can be used just like the ColourMatch. All the parameters are completely animatable, except the curves overlay on/off, because that would just be silly.
You can also use it for multi-coloured ramps, just attach it to your favorite Ramp or RGrad & change the Destination to the colours you want and position them with the Source pallettes luminance/gray values.
yaddah, yaddah, etc... have fun.

-fixed the 2.4x crashing when overlaying curves-

-fixed the fix that then caused shake 4.x to give warnings about 'recursive evaluations'-
