# Description     : Show values of EV3-leds
# Version         : v1.3  
# Date            : 2014-11-04
# Usage           : showleds
# Notes           : No arguments needed nor used       
#                   o brightness is only non-zero at the time
#                     that the led indeed *is* giving light.
#                     So a blinking led might show zero or non-zero.
