very basic cgminer-rpc.py

This works for me, but as always, YMMV

There are little things still @todo for the command line
but the class should be enough to do everything you need

basic localhost usage: ./cgminer-rpc <command>

Cool script, I made cgminer-monitor using your code: https://github.com/shazbits/cgminer-monitor/

not sure if you know about optparse lib? makes it very easy and convenient to parse arguments and includes help formatting automatically. you may know about it, but I figured i'd toss you some info anyway .. I've been using your class to pull info from cgminer. it helps very much! great work

I Need the same thing in C# immediate, if any body have than please help me.
