Merge pull request #138 from minrk/master

some work on Python examples
added final example from "inter-broker routing"; minor code clean-up for guide chapter 3
Merge pull request #139 from pblasucci/master

Updated F# examples
zhelpers.py adjustments

* zhelpers.dump(msg_or_socket) accepts multipart message *or* sockets,
  so that it matches the zmsg_dump behavior as well.

* add zpipe for zthread_fork-style creation of a pair of inproc PAIRs,
  for communicating across threads.

* My previous change to zhelpers.dump was imprecise,
  only hexlifying if characters were outside ascii,
  when it should have also protected against the low-end,
  which is still within ascii.
add Python majordomo examples

* first synchronous version
* tripping benchmark
* mdcliapi2/mdclient2 async client
* mmiecho/titanic/ticlient
Merge pull request #140 from minrk/py

Python majordomo examples
Titanic / mdcliapi tried to send message twice; fixed
Fixed examples to work with new zloop API
Added more Python and F#
add Python titanic example
add bstar2 (class/reactor-based) Python example

fixed a bstarcli.py bug where the poller was not updated to poll
the new client after it was created, so would perpetually failover.
