TODO: fix storeage service, add logging
npmignore file
New new simplified conception of the node.js framework.
Based on the requests from diunko@

 - simple communicator object
 - raw send()
 - new channel
 - new JS methods
example was updated
new useful files
obsolete files
handle code and reason of terminate message
a very special method to unpack dealer-packed http request and to
return request body as node::Buffer
a little of housekeeping
Desired services api would look like this.
Note streaming storage features.
added optimist dependency
That's how it looks now:
We pretend to have streaming read from storage.
We resolve service methods dynamically.
Async resolution with callbacks would be dreadful, so some kind of
promise/future machinery is used.
Need for synchronous resolution yet has to be discussed.
despite we have service method table from Locator and parse incoming
cocaine messages at binding level, we need this to send any outgoing messages
base class for any service interaction
duplex stream that represents either one service method call either
worker method invocation
Worker class. That's it.
some useful stuff
services machinery
logger and storage services definitions
