Added package to construct MATLAB/Node connection

This package explains how to create a MATLAB connection with Node, and demonstrates usage through a small program that sends random bits to a MATLAB node class. Hopefully, it's both educational and useful for other members of the lab. 
Probably just has something to do with managing the lifetimes of the memory and multi-threading. You have to be extra careful in those situations. But generally, const& is preferred for complex (not primitive) data types.
