+/**
+ *
+ * @author cozzy
+ *
+ *  This is a converter for SiTrackerHit1D objects. It draws the hit segment
+ *  for each instance. 
+ *
+ * 1) To enable this converter, you must modify org.lcsim.util.heprep.LCSimHepRepConverter
+ *    by adding the line "register(new SiTrackerHitStrip1DConverter());" where 
+ *    all the other register statements are (you'll also have to import this class)
+ *
+ * 2) Since SiTrackerHitStrip1D implements TrackerHit, TrackerHitConverter will 
+ *    also fire and draw a marker for each of these. This can be disabled by 
+ *    modifying org.lcsim.util.heprep.TrackerHitConverter so that it ignores 
+ *    any hits that may be cast as SiTrackerHitStrip1DConverter (try-catch is 
+ *    your friend).
