/* Tree 
 * 
 * Styling Tree mostly means styling the TreeRow (dijitTreeRow)
 * There are 4 basic states to style:
 * 
 * Tree Row:
 * 1. tree row (default styling): 
 * 		.dijitTreeRow - styles for each row of the tree
 *
 * 2. hovered tree row (mouse hover on a tree row)
 * 		.dijitTreeRowHover - styles when mouse over on one row
 * 
 * 3. active tree row (mouse down on a tree row)
 * 		.dijitTreeRowActive - styles when mouse down on one row
 * 
 * 4. selected tree row
 * 		dijitTreeRowSelected - style when the row has been selected
 * 
 * Tree Expando:
 * 	    dijitTreeExpando - the expando at the left of the text of each tree row
 * 
 * Drag and Drop on TreeNodes: (insert line on dijitTreeContent node so it'll aligned w/ target element)
 * 		.dijitTreeNode .dojoDndItemBefore/.dojoDndItemAfter - use border style simulate a separate line
