Asynchronous Twitter Requests

Over the past three days I worked on making twitter requests asynchronous, which was not the case earlier, mainly due to the CURL calls in libtwitcurl library. The main idea - "Run each request in a separate thread without blocking the main thread". One of the main tasks was to create a generic thread pool framework that provides an easy, clean interface to manage thread life-cycle. The next task was to re-write/re-organize some of the existing code to create requests that can make use of  this thread pool library, thus allowing multiple requests to run concurrently without blocking the main thread. The end result: Twitter-Backend is now more scalable and robust!
