NodeWidget class
A Simple widget to display TreeNodes in the TreeView.
Includes the indentation of nodes, the addition of Lines (if applicable) and the leading NodeWidgetLeadingIcon that already expands/collapses the node and animates itself.
This widget will be wrapped in a TreeNodeScope (an inherited widget) to give access to it's TreeNode.
