Use Cyclone & Python-Twisted instead of Tornado

[jkoshy]

Use Cyclone instead of TornadoWeb, for the front end in the Python prototype. Cyclone is built over Python-Twisted.

The benefits would be:

• The convenience of the twistd driver program.
• Improved asynchronicity.

And, by the way, current version of cyclone running with twisted 10x or 11x is actually faster than Tornado.

Thanks, all the more reason to consider Cyclone+Twisted then.
