* @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
