###   PROXY TOOLS 1.0
###   by Brian Willard
###   mybikeislost@gmail.com
###
###   Generates reformat and write nodes for rendering proxies on a farm
###   option to process all read nodes, selected read nodes, or all quicktime files in a script 
###   reads metadata to determine filetype to handle quicktime files with and without and extension.
###   process sequences proxy subfolders
###   option to create a read node that reflects the new proxy/fullres path
###   TODO: add support for r3d files
###
