[stringtemplate-interest] visualizer mockup

[Terence Parr]

Hi gang.  In order to produce 1 GUI (in Java I guess), Python and C#  
targets will have to get data to it.  That means a text or binary  
marshalling protocol. no way around it. we either write it or reuse  
existing one. In java, i can just pass the objects which is how I'll  
start.

I have a nice  prototype of debug info going.  First, ST bytecode  
compiler always generates instructions that know which expression in  
template they are executing.  This is good for errors and lets me  
track info for GUI.  I am collecting objects now that know the exact  
output generatd for the exact part of the template source; knows all  
attribute values etc....  A little clean up and I can try a braindead  
visualizer that highlights text for each template/expression in an  
textpane
