Feature: Table data streamer over socket

[dilawar]

Currently moose.Streamer allows streaming data to a csv file. This ticket track the progress of following:

• [x] moose.Streamer should stream to a socket Socket streamer should be independant of it. May be moose.TCPStreamer is a good class which is always created by shell whenever functionality is available.
• [ ]If portability (with windows) is an issue at all then consider boost library which has cross-platform implementation of sockets. Otherwise stick to unix sockets.
• [x] Stream only when a connection is made by client e.g. FindSim web interface.
• [x] Stream in json format.
• [x] More than one client should be supported. All client get the same data. Only 1 client is supported.
• [x] By default send data from all tables as (tablepath,t,value) { tablepath : [[t1,v1], [t2,v2]]}. Using default %g format. User should be able to change the format. Default format should have enough accuracy be suffient for web display.
• [x] Some benchmark on speed. NONE DONE.
• [x] Do we need to compress json before streaming. Needs some data on potential cost and benefits. PLAIN TEXT JSON
• [x] Port number to open the socket or use UNIX socket? PORT NUMBER 311416 by default.
• [x] Should we use boost for this? NO Using default headers e.g. sys/socket.h etc.

@surbhit21 Have a look at this ticket. In case, I've missed something essential, let me know.

Hey Dilawar, Can we restrict it to only specific web clients, like FindSim-web only for now, so that we have control over who can plugin to this socket?

PR #345 implements this. See the notes on this PR.
