TreeViewTheme class

A simple class to control the theming of TreeView.

Makes it easy to customize NodeWidget and LinesWidget.

Example of indent & lineThickness relationship.

 /*             <- indent ->
   -------------------------------------
   |                 |                 |
   |                 |                 |
   |               <-|-> lineThickness |
   |                 |                 |
   |                 |                 |
   -------------------------------------  */

A single line will be drawn at the middle of indent with thickness of lineThickness as shown above.

Play around to find the combination of values that better fits you.

Make sure indent >= lineThickness.
