Introducing feature "What's Interesting..." A QML based test interface has been designed.
SkyObjListModel is a subclass of QAbstractListModel. Objects of SkyObjListModel can
represent any sky-object(any type). Currently test models for Planets, Stars, Galaxies,
Constellations, Star Clusters and Nebulae are used in class Modelmanager. The QML UI is
maintained by the WIView class.

The models are loaded everytime "What's Interesting..." is opened. It takes a long
time to load all the models. This is because currently the models checks through all
sky-objects. A reduced list will definitely be required.
