LISTSERV 16.5 - HPS-SOFTWARE Archives

I figured out a different approach to this; when reading LCIO events from a
file, every object in there has to be converted, and a converter must be
present.  So I just created a dummy converter for the type of object that
existed in the file but the converter wasn't available.  this way i didnt
have to mess with hps-java, and was able to just use my own main method.
