/** @file AppContext.cpp
* @author Yann yann@ethdev.com
* @date 2014
* Provides access to the current QQmlApplicationEngine which is used to add QML file on the fly.
* In the future this class can be extended to add more variable related to the context of the application.
* For now AppContext provides reference to:
* - QQmlApplicationEngine
* - dev::WebThreeDirect (and dev::eth::Client)
* - KeyEventManager
