I have wrapped ofstream, so ascii tracing works.

However, it is notably not "reference counting safe" like python programmers
are used to, and if the ofstream object goes out of scope things could crash.
Example:

def configure_tracing():
  f = ns3.ofstream("foo.tr")
  ns3.YansWifiPhyHelper.EnableAsciiAll(f)
  # <-- f goes out of scope and is deleted

def main():
  #...
  configure_tracing()
  ns3.Simulator.Run() # <-- will crash


But, well, at least now ascii tracing works in python, it's better than nothing
:P
