  for each selected object, list all the connections of type 'animCurve'
  for each of the connected animCurve nodes, shortlist those with 'rotateX' in their names

connectAiLightFilters
Written by: Patrick Woo ([email protected])
Version: v02
Date: 20190307

--- Description ---
This tool connects Arnold light filters (decay, gobo, blocker, barn door) to Arnold lights

This is especially useful when we want to duplicate many lights, which are all connected to the same

def lineup_cam_grp(solveGrp, targetCamXform, startFrame=993):
    '''
    This function takes a freshly imported solve and lines it up to an existing camera,
    matching position and rotation.
    
    These are the things that happens in the script

# 20190204_maya2017_renderLayersReorder_v002
# Written by Patrick Woo ([email protected])

# this script reverses the order of render layers in the new Render Setup Window in Maya 2016 and above
# the scene must have at least 2 render layers to see the re-order effect

# changes:
# - the first item in the list can now be re-ordered just like the rest of the layers, by first detaching then re-attaching
# - this version allows re-ordering every render layer by first detaching them (previously there was no detaching)
# - if you have the Render Setup Window open, the layer order now reflects and refreshes without having to re-open the window

'''
Problem:
keyframes from camera tx, ty, tz, rx, ry, rz ranging from 1001 to 1195
need to have their timing remapped, such that the new timing is sped up by 2x
thus, the formula where kT = original frame, is ((kT - 1001) * 0.5) + 1001
This will give us new keyframes from frames 1001 - 1098.

New frame range after re-speed is 1001 - 1093, we just truncate frames 1094 - 1098.
