[kepler-dev] fileOrURLPort broken in BinaryFileReader ?

Hi Tristan,

The problem was with the port value being read in the initialize method 
instead of in the prefire.The initialize method is called for all the 
actors as the user hits the run button prior to the 
prefire/fire/postfire iterations, thus, since the preceding actor hasn't 
fired yet, the BinaryFileReader port doesn't have a token available. I 
updated the code and checked it in to CVS.
