Ignition Robotics Transport Library - Add more features to the main library

by Konstantinos Chatzilygeroudis for Open Source Robotics Foundation

The objective of the project is to implement additional features to the main library of the IGN Transport library. This includes implementing the ability to send/receive compressed messages, adding authentication and encrypted data and enabling latching. The long term goal is for IGN Transport to become a powerful, yet lightweight, library for the communication layer of robotics applications.
