* IRremote
* Version 0.1 July, 2009
* Copyright 2009 Ken Shirriff
* For details, see
* Edited by Mitra to add new controller SANYO
* Interrupt code based on NECIRrcv by Joe Knapp
* Also influenced by
* JVC and Panasonic protocol added by Kristian Lauszus (Thanks to zenwheel and other people at the original blog post)
* LG added by Darryl Smith (based on the JVC protocol)
