-# Tree
-
-Unlike Table, Tree can only store a set of a single data type. (Blame Windows.)
-
-```go
-type TreeData struct {
-	Checked		bool
-	Image		ImageIndex
-	Text			string
-	Children		[]TreeData		// TODO does this need to be *[]TreeData?
-}
-```
-
-(the facilities for Images has yet to be designed)
-
-Tree itself will operate similarly to Table:
-
-```go
-type Tree struct {
-	Control
-	sync.Locker		// with Unlock() refreshing the view
-	Data() *[]TreeData
-	SetHasCheckboxes(bool)
-	SetHasImages(bool)
-}
-```
-
-By default, a Tree only shows the Text field.
-
-A Tree path is just an `[]int` with each element set to the consecutive index in Children. For example:
-
-```go
-i := []int{3, 4, 5}
-value := tree.Data()[i[0]].Children[i[1]].Children[i[2]].Text
-```
