Simple example of using a tree view
Some more missing classes to be imported
A fairly complex example of tree view with drag and drop support
New default converter argument (pushing API to limits). drag_event converter
Fix bug when dragging on part of tree view which has no tree_items.  Also make tree view editable
Short-hand set_effect to just effect.  Add inset converter and use it for padding so you can pass in single numeric instead of having to explicitly create an insets object
Add nicety similar to groovyfx where you can specify array format for insets where 1 is top/bottom/left/right, 2 is top/bottom, left/right, and 4 is top, right, bottom, left
Add rectangle2d coverter
Fixed GH #19.  New don't add me sigil for DSL using bang
