Change the transparency levels on all layers inside of your current ArcMap MXD document in one fell swoop!

	##################################################################################################################
	#
	# Requirements: You'll need ArcGIS Desktop 10.1 or higher with Python 2.7+
	#
	# If you want to change Transparency for all the layers in your ArcMap MXD quickly, this will do the trick.
	#
	# 1. Copy / Paste the initial commands and function definitions below into an MXD's Python command shell, one-by-one
	# 2. Use the command "setLayerTransparenciesTo(75)" to change every transparency to 75, or whatever you want
	# (As a side note, notice that the Group Layers are set to 0 transparency. Play with this if you want!)
