time_grab.rb

#1. Read in files, one at a time (remove first 10 junk lines)
#2. Start looking at data at 90 ns...strikes start at 100ns
#3. Raise flag if output drops below 90% of max (1 V) and record time (t1)
#4. If the flag is raised, record time (t2) when output goes back above 90%
#5. Reset flag
#6. Record t2-t1
#7. Ouput Node name, LET, number of flags in file, duration and time of flags
