Separating Observable and Controller
Merge branch 'dev' of https://github.com/janouna/LeapMotionPresenter into dev
Refactoring SelectedHandler
- Moving code around to better structure the selectedness handler for different button actions
- Some testing of the Slide object and a basic Image object positioning within slide
- It seems that due to the nature of Parent class, StackPane.Alignment should be set to Pos.TOP_LEFT for true absolute positioning
