HOWTO: Check the sanity of fzd files

$ starsim -w 0
starsim > gfile p some.fzd

First load an event into memory with
starsim > trig 1

Next print out kinematic information (event generator)
starsim > gprint kine

Next print out hits
starsim > gprint hits

Anything that can be printed using gprint is stored in the fzd file and can therefore be printed...
starsim > help gprint
