This object might contain tree selection and expand states for all loaded tree nodes. Usually this object is constructed through TreeUtils automatically and could be applied to some tree using these utilities aswell. @author Mikle Garin @see TreeUtils

Manages the state on a Tree:
1. selection: selected tree-nodes
2. expandState: open/close folder state
3. marker: last used action object
