Summary

Public constructors
`<init>(root: VNode)`

Public methods
Unit	`insertBottomUp(index: Int, instance: VNode)` Indicates that instance should be inserted as a child of current at index.
Unit	`insertTopDown(index: Int, instance: VNode)` Indicates that instance should be inserted as a child to current at index.
Unit	`move(from: Int, to: Int, count: Int)` Indicates that count children of current should be moved from index from to index to.
Unit	`remove(index: Int, count: Int)` Indicates that the children of current from index to index + count should be removed.

Protected methods
Unit	`onClear()` Called to perform clearing of the root when clear is called.

Inherited functions

From class AbstractApplier

`Unit`	`clear()` Move to the root and remove all nodes from the root, preparing both this Applier and its root to be used as the target of a new composition in the future.
`Unit`	`down(node: T)` Indicates that the applier is getting traversed "down" the tree. When this gets called, node is expected to be a child of current, and after this operation, node is expected to be the new current.
`Unit`	`move(from: Int, to: Int, count: Int)`
`Unit`	`remove(index: Int, count: Int)`
`Unit`	`up()` Indicates that the applier is getting traversed "up" the tree. After this operation completes, the current should return the "parent" of the current node at the beginning of this operation.

From class Applier

Unit

insertBottomUp(index: Int, instance: N)

Indicates that instance should be inserted as a child of current at index. An applier should insert the node into the tree either in insertTopDown or insertBottomUp, not both. See the description of insertTopDown to which describes when to implement insertTopDown and when to use insertBottomUp.

Unit

insertTopDown(index: Int, instance: N)

Indicates that instance should be inserted as a child to current at index. An applier should insert the node into the tree either in insertTopDown or insertBottomUp, not both.

The insertTopDown method is called before the children of instance have been created and inserted into it. insertBottomUp is called after all children have been created and inserted.

Some trees are faster to build top-down, in which case the insertTopDown method should be used to insert the
