'''RECEIVING PACKETS, PROCESSING, AND DISPATCHING:'''

14:07 descention packets seem to be in a format of: type,source,dest,userID,payload,options 14:08 descention which might be of these types (in order):int,tuple,tuple,int,buffer,dict 14:09 descention i'm not sure about the source,dest types 14:18 shanemse tuple is python code.. 14:18 shanemse http://en.wikibooks.org/wiki/Python_Programming/Tuples 14:22 descention in c++ objects: PyInt?,PyTuple?,PyTuple?,PyInt?,PyBuffer?,PyDict? 14:22 descention the PyTuples? might be PyAddress? 14:24 descention I figured out most of that from the packet encode. line 267 of PyPacket?.cpp
